• Routing multiple static IPs from ISP at the cable modem?

  - by Jakobud

  I'm taking over IT responsibilities for a previous IT guy. We have a 50mb cable modem connection from Comcast along with 5 static IP addresses: XXX.XXX.XXX.180 XXX.XXX.XXX.181 XXX.XXX.XXX.182 XXX.XXX.XXX.183 XXX.XXX.XXX.184 We are in the process of replacing our firewall machine. Currently the firewall box is the only thing connected to the cable modem. However the cable modem has multiple ethernet ports on it, similarly to a router. I have assembled a new firewall machine and its time to start testing and configuring it. So that means that I also need it plugged into the cable modem (remember it has multiple ethernet ports on it). So now with multiple computer plugged into the cable modem, how does the cable modem know where to route the traffic? If some request on the internet is made to XXX.XXX.XXX.181, which goes to our cable modem, how does the cable modem know which connected computer that traffic is supposed to be sent? Looking at the web interface for the cable modem, there doesn't seem to be anything special setup on it with regards to routing or NATing IP addresses. Is that because when there is only one computer connected to the modem, all traffic is sent to it by default? Now that I am going to (temporarily) have multiple computers plugged into the cable modem, do I need to specify routing or NAT rules on the modem itself? I am going to speak to Comcast about this next, but I figured I'd ask here first just so I can get a better grasp on how this type of thing generally plays out.

• Creating an Excel 2007 bubble chart with date values in axis

  - by Shadowfoot

  I'm trying to create a graph showing the duration of issue resolution. I believe a bubble chart in excel will show what I want but I can't manage to get it working correctly. For each date I have a number of days (duration) and a number of issues (magnitude). Most dates have a duration of 1 with a large magnitude, and I want to avoid the outliers dominating the chart. e.g. 1-Feb, 1, 15 1-Feb, 2, 10 1-Feb, 9, 1 2-Feb, 1, 11 2-Feb, 2, 14 2-Feb, 6, 2 2-Feb, 18, 1 etc. I want the data in this example to give me 2 columns of bubbles. When I try to get excel to create the chart I can't get the date to appear at on the x axis; I get a count (representing the row of the data) instead, and as each row is a separate column, the values don't line up for the date. Can this be done in Excel 2007 without using VBA?

• Map a domain to another subdomain - Rackspace

  - by Gorgi Rankovski

  I am using a subdomain as a parameter to an ASP.NET MVC 4 application. It's working well. Now I need to test my approach, so I have the application hosted on appharbor. It works well with subdomains here too. Our DNS registers are on Rackspace, but I have no control over it. Another guy is responsible for that. So, myapp.apphb.com can be accessed through myapp.com. Also abc.myapp.com is working as expected. I use abc as a parameter. So, now I want abc.com to be mapped in those Rackspace DNS registers to abc.myapp.com Is this possible at all? Can you explain to us how to do that? Will I have some problems with it? Anything that I should be aware of? Please have in mind that I am newbie when it comes to DNS. And no experience with Rackspace. Thanks.

• HP Procurve Issue Passing Multiple VLANs over a link

  - by MichaelRwat

  Just to start off with I am a Cisco guy that got placed into an HP project. Basic topology overview from outside in: ASA 5505 with two Ethernet connections to a 2910-24 port switch. This switch is then (Cisco Trunking) to a 2626 switch passing vlan (1 untagged and 100 tagged)between them. I created SVI's on each of the switches for both VLAN's for testing purposes. I can not get vlan 100 to pass across this link. I also have trunks configured to AP's off of the switch and can not ping the vlan 100 BVI on the AP's but can reach the vlan 1 BVI. Port 25 on Access layer (2626) connects (trunks) with port A1 of 2610. STP is not running at all on any switch (this is not my network I can't change this nor did I design this) Distribution Sw: MP1-0# show run ip default-gateway 10.100.100.100 vlan 1 name "DATA" untagged 1-22,24-A1,B1 ip address 10.100.100.6 255.255.255.0 no untagged 23 exit vlan 100 name "GUEST" untagged 23 tagged 24-A1 ip address 10.100.102.6 255.255.255.0 exit Access Sw: ip default-gateway 10.100.100.100 vlan 1 name "DEFAULT_VLAN" untagged 1-26 ip address 10.100.100.5 255.255.255.0 exit vlan 100 name "GUEST" ip address 10.100.102.5 255.255.255.0 tagged 15,25 exitt From the ASA I can ping the vlan 100 address of the 2610 but not the 2626 (10.100.102.6)[Not passing the "trunk"] If I plug into an access port vlan 100 of the 2626 I can ping the SVI for vlan 100 as intended. I can not ping across the "trunk" over vlan 100 but I can across vlan 1. There may be something obvious I'm missing but please review my configuration and thank you for the assistance.

• 4.00gb (3.25gb usable) in Windows 7 x64

  - by dotnetdev

  Hi, I have setup Windows 7 Ultimate x64 on my PC. I have 4gb RAM and my BIOS states the correct amount (4096mb), but I cannot Windows (System Manager) says I have 4.00gb (3.25gb usable). This seems to be a popular issue, and I have looked for an integrated video card (integrated with my chipset) to disable but haven't found anything. What else can be preventing me from seeing all 4gb? When I had Vista 32bit, it would say 3.25gb RAM not 4.00gb (3.25gb usable). I have an x64 CPU and when I brought my RAM, I used a compatibility tool from Crucial (the memory vendor) to test how much memory my PC can support and 4gb was the answer (this was a windows app I think). Chipset is Intel(R) G33/G31/P35/P31 Express Chipset PCI Express In the bios, I looked for an onboard video card (integrated) and there was no such thing, but a couple of other onboard devices. There are also no "Resource Mappings" settings. FURHTER DETAILS: Chipset North Bridge: Intel Bearlake G33 South Bridge: Intel 82801IR ICH9R Maximum Memory Amount 8 GB Graphics Controller Type Intel GMA 3100 (Enabled) I guess the first thing is, how do I disable the graphics controller? EDIT: This thread (http://forums.legitreviews.com/about23417.html) indicates the issue is with memory mapped devices, but someone on this thread says that does not apply to x64. The rest of the comments points to a mobo issue for the guy who started that thread. Thanks

• Gantt Chart online

  - by Luca

  I need to insert a horizontal bar chart in a web page. The thing I have to do is very similar to a Gantt Chart. I'd like to use a javascript library for the purpose. I tried jsgantt, but actually it is not very beautiful. I could evaluate also a server generation of the graph. In case my server side language is Python. It will be part of an internal project with no internet access, so Google Charts isn't an option.

• Find coordinate by angle

  - by George Johnston

  I am developing in application in XNA which draws random paths. Unfortunately, I'm out of touch with graphing, so I'm a bit stuck. My application needs to do the following: Pick a random angle from my origin (0,0), which is simple. Draw a circle in relation to that origin, 16px away (or any distance I specify), at the angle found above. (Excuse my horrible photoshoping) The second circle at (16,16) would represent a 45 degree angle 16 pixels away from my origin. I would like to have a method in which I pass in my distance and angle that returns a point to graph at. i.e. private Point GetCoordinate(float angle, int distance) { // Do something. return new Point(x,y); } I know this is simple, but agian, I'm pretty out of touch with graphing. Any help? Thanks, George

• Algorithm and data structure learning resources for dynamic programming

  - by Pranav

  Im learning dynamic programming now, and while I know the theory well, designing DP algorithms for new problems is still difficult. This is what i would really like now- A book or a website, which poses a problem which can be solved by dynamic programming. Also there is the solution with an explanation available, which i would like to see if i cant solve the problem even after butting my head at it for a few hours. Is there some resource that provides this sort of a thing for several categories of algorithms- like graph algorithms, dynamic programming, etc? P.S. I considered Topcoder, but the solutions there are not really appropriate for learning to implement efficient solutions.

• Load nsimage from url but only some url's work

  - by happyCoding25

  I have some code that loads an image file off the web and puts it in an image view. The problem is it works with everything but Google Charts. This is frustrating because I was relying on this to graph data for my app. Heres the url I need to load: Click to see my test chart. Im not sure why NSImage seems to refuse to load this when it works with everything elese. If you know why or have a work-around any help is appreciated. Heres some sample code I found that I'm using to load the images: NSURL *imageURL = [NSURL URLWithString:@"http://chart.apis.google.com/chart?cht=p3&chs=700x400&chd=t:20,20,20,20,20&chl=A|B|C|D|E&chco=66FF33,3333CC"]; NSLog(@"url"); NSData *imageData = [imageURL resourceDataUsingCache:NO]; NSLog(@"data"); NSImage *imageFromBundle = [[NSImage alloc] initWithData:imageData]; (Note: This code will load any image except a chart) Thanks

• [[UIDevice currentDevice] orientation] always null

  - by Toby Wilson

  As per the title. Calling [[UIDevice currentDevice] BeginGeneratingDeviceOrientationNotifications] has no effect. DidRotateToInterfaceOrientation etc events are working fine, but I need to be able to poll the device orientation arbitrarily. How can I fix/do this? The long story: I have a tab application with a navigation controller on each tab. The root view of tab number one is a graph that goes full screen when the orientation changes to landscape; however this needs to be checked whenever the view appears as the orientation change could have occurred elsewhere, so I was hoping to poll the orientation state whenever this view appears.

• Windows 2003 Active Directory Integrated DNS zone not registering non-domain computers

  - by Jeff Willener

  I'm not a networking guy by all means, I'm just a developer who dabbles enough to get into trouble and I'm there. So bear with me... :) At my office I have a Windows 2003 Domain Controller which also services DNS. On the domain I have a handful of computers and other misc. equipment/toys. For the DNS I only created a Forward Lookup Zone for my domain (mydomain.com). I run a lot of VM's so generally I have everything on the domain, however some of those VM's are not and only in a 'Workgroup'. I also have another laptop which belongs to another domain (otherdomain.com) which is here 100% but I use it for other purposes and has to belong to the otherdomain.com. With all that said, I have two questions: I have found any computer not on mydomain.com does not register it's IP address even though 'Register this connections address in DNS' is set to in the 'Advanced TCP/IP Settings' for the nic. Where have I messed this up? On the laptop which is registered on otherdomain.com, when I do a nslookup for a computer on mydomain.com (e.g. nslookup devbox1) it appends otherdomain.com as the suffix (e.g. queries devbox1.otherdomain.com). Same thing occurs if I use the fully qualified name. In the 'Advanced TCP/IP Settings' for that nic, I can 'Append these DNS suffixes' of mydomain.com but I fear that will hose my DNS lookups when I VPN to otherdomain.com. So what is the correct approach to resolve this issue? Do I add both mydomain.com and otherdomain.com in that order?

• file_get_contents() returns "failed to open stream" when used with Facebook access_token flow

  - by TMC

  file_get_contents() is returning "failed to open stream" when I call it on a Facebook oAuth access_token URL. Warning: file_get_contents(https://graph.facebook.com/oauth/access_token?client_id=XXXXX&redirect_uri=http://mydomain.com/fb/callback3.php&client_secret=xxxx&code=YYYY) [function.file-get-contents]: failed to open stream: No error in E:\\htdocs\fb\callback3.php on line 5 (I have removed ClientID, clientSecret and the oAuth Code). If I try to manually hit the Facebook access_token URL that my code is attempting to fetch, I get an actual payload returned in the browser: access_token=XYZ&expires=6508 (where XYZ is the access token) So for some reason, there is a problem with the access_token URL specifically when used with file_get_contents(). At first, I thought it was a security issue with my webhoster, but I have verified with phpinfo() that allow url open is indeed allowed. I have also tried this code and verified it works: $foo = file_get_contents('http://google.com'); echo $foo Anyone have any ideas why file_get_contents() is failing with the Facebook access_token URL?

• Does there exist a jQuery plugin or JavaScript library that allows Venn Diagram presentation?

  - by knowncitizen

  I'm writing a jQuery application to allow analysis of data with the help of visual cues. My data is retrieved via XMLHttpRequest in the form of JSON. The visual cues include histograms, spark lines, and various other graph types. The idea is that the user is able to narrow their data via these various visual views. My question is thus - aside from the Google Charts API, does there exist a JavaScript way of presenting a Venn Diagram? Requirement: no Flash. Canvas is acceptable.

• OS/X 10.6 Bizarre login bug: Making alternative "Others..." appear. Why does this happen?

  - by bjornl

  I am studying at NUS in Singapore, and they have a mac-equipped computer lab here at school. All users (students) have our own personal accounts that we use to log in to the computers with. Sometimes when you approach a computer to log in only the alternative "thinkmac", which is the school's administrator account, I presume. Some other computers have the alternative "thinkmac" as well as "Others..." where you can input your own login credentials. One day as I sat down by a computer and there was only the "thinkmac" alternative. I was about to get up and find another one when the guy sitting next to me says - Just click 'thinkmac' - the computer will ask for your password - then hit escape to get back to the login screen. Repeat until "Others..." appear. So: If you click any user account, hit ESC to get taken back to the login screen, repeat for 5-10x, eventually the alternative "Others..." will appear. Why is this? Is there an internal counter that keeps track on how many times you have clicked a/any given user account, and after a certain threshold it displays the "Others"? What is the logical reasoning behind this?

• Problem configuring php-fpm with nginx

  - by Nisanio

  First of all: I'm not an expert in configuring things. This is very new for me, so, my apologies in advance. At work we have a Centos server. The guy who worked here before installed nginx. We need to made a php site, so, obviously, I need to set up php and make it work with nginx. Making short a very long tale, I had to replace the nginx binary with a new one (because the older was compile without fast-cgi), and I had to recompile and install php (because the new version has fpm). Then I struggle with the config files, making this nginx.conf (not all the file) user php; location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; include fastcgi_params; } and uncomment some parameters in php-fpm (to much to detail here, but the important is that group and user are "php") I never could start the php-fpm with the instructions of the book sudo /usr/sbin/php-fpm start But after look at the net, I found this sudo /usr/local/sbin/php-fpm --fpm-config=/usr/local/etc/php-fpm.conf This worked (I think) I restarted nginx. But... nothings happens with php... My calls to php files (via firefox) doesn't even appear in the log (/opt/nginx/logs/error.log) I'm really, really exhausted and lost... Could anyone help me, pleaaase.... :( Thanks in advance

• In LINQ-SQL, wrap the DataContext is an using statement - pros cons

  - by hIpPy

  Can someone pitch in their opinion about pros/cons between wrapping the DataContext in an using statement or not in LINQ-SQL in terms of factors as performance, memory usage, ease of coding, right thing to do etc. Update: In one particular application, I experienced that, without wrapping the DataContext in using block, the amount of memory usage kept on increasing as the live objects were not released for GC. As in, in below example, if I hold the reference to List of q object and access entities of q, I create an object graph that is not released for GC. DataContext with using using (DBDataContext db = new DBDataContext()) { var q = from x in db.Tables where x.Id == someId select x; return q.toList(); } DataContext without using and kept alive DBDataContext db = new DBDataContext() var q = from x in db.Tables where x.Id == someId select x; return q.toList(); Thanks.

• Acer Aspire one is falling apart on Ubuntu

  - by Narcolapser

  Question: How do I have my netbook detect and install hardware? Info: I have an Acer Aspire One, it came with windows XP and I loaded it with Win7. I decided I wanted to change to Ubuntu so I tried Ubuntu netbook remix, which failed horribly, and so after attempting 3 or so other OS's I ended with Ubuntu Desktop 9.10. Which worked fine for a while, but there were some minor issues so I asked a question about it here and decided to change my OS again. This last weekend I tried mandriva like that guy in my other question suggested, no success. when I had though my netbook lost the ability to use it's touch pad, I didn't think much of it, just thought it must be a driver or something. But When Mandriva failed, and I also while I was at it tried Damn small linux and Debian, which both failed to, I decided to switch back to Ubuntu Desktop(some where in here my keyboard stopped working for one attempt to). But first I gave the netbook remix one more try. it worked this time, with the exception of it didn't have any networking. I thought it was a driver issue again and finished the weekend with ubuntu desktop 9.10 again. But now things get really crazy. it doesn't know it has a wireless card or an ethernet card. It doesn't know my phone is connected trying to provide wireless broadband either. I'm clueless on what could be the problem. And with only a minimal amount of experience with Ubuntu can't navigate the entire interface with only my keyboard(it doesn't detect a USB mouse when I plug it in, it had when I installed it. in fact the network interfaces were working just fine when I live boot ubuntu to installed it). Even so, I don't know where to go or what to do to make it recognize it's hardware. I'm in a dire situation, any help is welcome.

• How to configure TFTPD32 to ignore non PXE DHCP requests?

  - by Ingmar Hupp

  I want to give our Windows guy a way of easily PXE booting machines for deployment by plugging his laptop into one of our site networks. I've set up a TFTPD32 configuration which does just that, and our normal DHCP server ignores the PXE DHCP requests due to them having some magic flag, so this part works as desired. However I'm not sure how to configure TFTPD32 to only respond to PXE DHCP requests (the ones with the magic flag) and ignore all normal DHCP requests (so that the production machines don't get a non-routed address from the PXE server). How do I configured TFTPD32 to ignore these non-PXE DHCP requests? Or if it can't, is there another equally easy to use piece of software that he can run on his Windows laptop? Since the TFTPD part is working fine, a DHCP server with the ability to serve PXE only would do. Worst case I'll have to set up a virtual machine with all this, but I'd much prefer a small, simple solution. I'm not interested in solutions that involve using the existing DHCP servers or separating machines on the network for deployment, the whole point is to be simple and stand-alone.

• Generating a Call Hierarchy for dynamicly invoked method

  - by Maxim Veksler

  Hello, Today's world of dynamic invoke, reflection and runtime injection just doesn't play well with traditional tools such as ctags, doxygen and CDOC. I am searching for a method call hierarchy visualization tool that can display both static and dynamic method invocations. It should be easy to use, light during execution and provide helpful detailed information about the recorded runtime session. Now I guess Callgrind could be considered a valid solution for the family C. What tool / technique could you suggest to create a call graph for both static and dynamic method invocation for JVM based bytecode? The intended end result is a graphical display (preferably interactive) which can show path from main() to each method that was invoked. During research for this post I stumbled upon javashot, it seems that this is the kind of approach I'm aiming at, I would prefer that this would be integrated into a kind of profiler or alike which than can be used from within my IDE (Eclipse, IntelliJ, Netbeans and alike). Thank you, Maxim.

• SVN problems after migration with CVS2SVN

  - by Bjorn C

  We´ve migrated from CVS on AIX to SVN on Linux via CVS2SVN. The migration seems to have went well but when working in SVN we get a lot of Tree Conflicts that doesn´t seem to be conflicts at all? Looking at the revision graphs, one can see that the graph for e.g. trunk and a branch isn´t the same, i.e. they contain different sets of revisions of the file. Either of the 3 ways to resolve this conflict when merging in TortoiseSVN leaves the revision graphs separate, they cannot be "melted" together. Could it be that CVS2SVN didn´t understand that a file in different branches is the same even if the file system path is the same? Anyone who has experienced this? Thanks, Bjorn

• how to show legend in graphs using flot

  - by robezy

  Hi, I'm using flot library to show plot graph. I need to show the legend in a separate div. Quoted from flot api. If you want the legend to appear somewhere else in the DOM, you can specify "container" as a jQuery object/expression to put the legend table into. So i wrote the legend options as below. "legend":{"show":true,"container":"jQuery("#placeholder")"}} Unfortunately it is not showing anything? is this the correct way of writing legend option? One good thing is it not showing default legend. so i guess the problem is with way i wrote the container . Any thoughts? Thanks

  Hi! I need to insert a Flash movie in a Visual Basic 2008 express form and send parameters to the movie, but am a newbie to VB. The flash movie will plot points sent by VB in a graph. I tried to insert the Shockwave Flash control in the form but cannot find it anywhere. So I inserted the webbrowser control, which I understand can be used to a similar purpose. But how would I send the values of X and Y (coordinates to plot in Flash) to the flash swf? Thanks for any help!

• Rebinding Keys on a Dell Keyboard

  - by Maarx

  I have a Dell Multimedia Keyboard, similar to this one: It has many non-standard keys, like the small circular ones across the top, and the "Multimedia" keys above INSERT/HOME/PAGE_UP. They can be rebound through simple registry entries. Some sample ones are included below: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey] [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\15] "ShellExecute"="C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe http://mail.google.com/mail/#inbox" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\16] "Association"=".cda" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\17] "ShellExecute"="C:\\Windows\\System32\\SnippingTool.exe" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\18] "ShellExecute"="calc.exe" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AppKey\7] "Association"="http" I've rebound the "MAIL" key to, instead of booting Outlook, to booting Firefox directed at my G-Mail account. I've rebound the button that would normally open "MY COMPUTER" to instead boot the Windows 7 "Snipping Tool", something I find very useful. Now, I'm looking to do some other things that I don't already know how to do. Note that answering this question doesn't necessarily require any knowledge about the keyboard or rebinding the keys: I can add, for any given key, a "ShellExecute" entry, and it will simply execute the following command as if it was typed at a Command Prompt. (I'm aware I dumbed that down rather significantly, but bear with me. I'm not really a Windows guy myself.) I use the volume knob for it's intended purpose, to change volume. I would like to change, however, a different key, to "reset" the Windows volume level back to exactly 50%, or, as it refers to it, "50", on it's 0-100 scale. I'm looking for the "program" (what I would type at a command prompt? these are still just Sys32 programs in the PATH, aren't they?) that, I imagine, would take arguments, to change Sound/Volume settings under Windows 7. Perhaps, for clarification, something that might take the form "C: SetVolume -slevel 50" or something.

• Need troubleshooting advice for intermittent dns problems with requests on isp nameservers

  - by Mnebuerquo

  I've been having some intermittent dns problems with a web server, where certain isp's dns servers don't have my hostnames in cache and fail to look them up. At the same time, queries to opendns for those hostnames resolve correctly. It's intermittent, and it always works fine for me, so it's hard to identify the problem when someone reports connectivity problems to my site. My website is on a server running linux with Plesk. My dns records are configured with plesk (so my server is its own dns master). Domain name is registered with godaddy. I'm not real knowledgeable about dns, so I don't really know how to begin with troubleshooting. I've started learning to use dig, but while I can read the manpage to learn the syntax, I don't really know what questions to ask. Since the problem is intermittent I haven't been able to really catalog many symptoms. Symptoms I have observed: Certain people repeatedly reported intermittent problems connecting to my website. This was only from certain networks. (Ex: One guy could connect reliably from his office but not his home.) Sometimes I notice my browser taking a long time looking up the hostname for my site (Firefox shows a message in the status bar at the bottom). For me this is in the ten second range. ssh connections from anywhere to my server take a long time to connect but then seem to work fine once connected. So hopefully the folks on serverfault can point me to a good beginner tutorial for understanding dns, and suggest troubleshooting questions to ask next time one of my users reports connectivity problems.

• Multiple IPs on firewall, are these virtual interfaces or what?

  - by Jakobud

  We have 5 static IP addresses from our ISP: XXX.XXX.XXX.180 XXX.XXX.XXX.181 XXX.XXX.XXX.182 XXX.XXX.XXX.183 XXX.XXX.XXX.184 On our firewall box, the NIC that is connected to our cable modem, appears to have all 5 IP addresses set on it. A previous IT guy set this thing up, and I'm not sure exactly what he did. Are these virtual interfaces on this NIC or what? Here is my ip addr output for that NIC: rwd0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether XX:XX:XX:XX:XX:XX brd ff:ff:ff:ff:ff:ff inet XXX.XXX.XXX.180/24 brd XXX.XXX.XXX.186 scope global rwd0 inet XXX.XXX.XXX.181/29 brd XXX.XXX.XXX.186 scope global rwd0:FWB9 inet XXX.XXX.XXX.182/29 brd XXX.XXX.XXX.186 scope global secondary rwd0:FWB10 inet XXX.XXX.XXX.183/29 brd XXX.XXX.XXX.186 scope global secondary rwd0:FWB11 inet XXX.XXX.XXX.184/29 brd XXX.XXX.XXX.186 scope global secondary rwd0:FWB12 inet6 fe80::250:8bff:fe61:5734/64 scope link valid_lft forever preferred_lft forever I'm a bit new to firewalls and networking so I'm just trying to figure out what he had going on here. I know he used Firewall Builder to configure the iptables rules, maybe that has something to do with the "FWB" I see in those names? So my questions are: What is going on here? Virtual Interfaces? Or something else? If we want to put in a second firewall in parallel with this firewall but we only want it to handle traffic to XXX.XXX.XXX.182, how do we get rid of the static XXX.XXX.XXX.182 address on this existing firewall box?
