• Problem with VPN using 2 Wire Router with a Linksys Router.

  - by Hiram Hubbard

  I am having a problem with a VPN between a 2 Wire router and a Linksys router. 2 wire is the client PC using Linksys Quick VPN software and Linksys RVS4000 is the server. The PC is not the issue. It works on a different network not using 2 wire. Also the Linksys RVS4000 is not the issue, 3 other user can VPN to it with no problem not using 2 Wire. The problem is with 2 Wire. The client PC is getting this error: "The remote gateway is not responding" What configuration changes are needed on the 2 Wire router (port, UPNP, etc...) and what changes are needed if any on the Linksys RVS4000? Thanks.

• Is it possible to have a wireless in-house NAS with wireless data transfer rates of equivalent to SATA speeds?

  - by techaddict

  Basically I would like to know, if it is possible to set up an NAS in my house to be accessed wirelessly, that can reach equivalent real-life data transfer speeds to USB 3.0 or an internal SATA hard drive. I have been wanting to do this for some time ( a couple of years now). Basically, this is what I want to do: Plug in a number of hard drives in an array, somewhere in my house, to be left plugged in and never have to be monitored. Ideally several terabytes. Whenever I am home, to have my computer and laptop configured to automatically find the NAS, as easy as plugging in an external hard drive - except completely wirelessly. Data transfer needs to be as seamless and quick as having added another internal hard drive in my laptop. Moreover, data should be able to accessed without having to copy it over - I should be able to wirelessly access the NAS and browse files, and open files directly from the NAS. For example, say I wanted to open a video - I should be able to play the video that is located on the NAS, directly from the NAS, completely wirelessly. If I wanted to open a .pdf file, I should be able to open it and read it directly from the NAS, as if it were located on my physical internal hard drive. Cost is important as well. Please tell me what equipment I need for this to be possible. I know you geniuses out there who can tell me if this is possible.

• How to use the AWUS036H on MacBook Pro with Lion and Backtrack in VM?

  - by Swader

  I have the AWUS036H USB WiFi adapter and have recently upgraded the OSX to Lion. The thing is, there are no drivers for Lion for the AWUS036H, and I would have to boot into 32bit mode every time I want to launch the adapter as per instructions here: http://www.youtube.com/watch?v=n9_HAGi1ce0 I also want to install BackTrack as I deal in networks a lot for my company. While this would be a simple matter on any other laptop, the company issued Macbook does not allow booting into any OS other than MacOSX or Windows with Bootcamp. Now, since dual booting into BT is not an option, I would like Backtrack to run in VM inside my MacOSX Lion - and this it does. It works like a charm inside VirtualBox. But since there are no 64bit drivers for the wifi adapter, Lion doesn't recognize it and cannot install it. This, in turn, means that Backtrack cannot see it even though AWUS036H usually works flawlessly with BT. How can I make my VM-based BT see the wifi adapter even if the parent OS doesn't see it, if at all? Is there a way, or am I better off buying a new WiFi adapter that supports OSX 10.7 such as the AWUS036NHR?

• Offloading Cable Modem operations to Router

  - by Matt

  I may be crazy here, but I seem to recall a conversation in the past stating that it was possible to offload some of the operations taken by one's cable modem to one's router. The logic was that since the cable modem is often equipped with a cheaper processor as it is supplied by your provider, that it often chokes even crashes when you start a torrent or something else with a lot of connections. I seem to recall that some routers offered the ability to take some of the modem's operations. Is this possible or have I imagined the whole thing? I ask because my modem seems to have many issues when I start torrents.

• Where do I learn about IP blocks and subnets? Or is there just a calculator that does it all for me?

  - by cwd

  Amazon's elastic compute tool (among others) requires the ip block format for their command: ec2-authorize websrv -P tcp -p 80 -s 205.192.0.0/16 I may be doing this wrong, but as far as I can tell I need to use the block format even for a single IP address. 1) So, how would I do that for this IP? 71.75.232.132 Several years ago I took a CCNA class, and I remember going over IPs and subnets, masks, broadcast addresses, class a/b/c networks, etc. However a lot seems to have changed since then - for example I don't think you can tell what "class" a network is in just by looking at it anymore - sometimes they could be multiple classes. 2) Anyhow, my second question is where do I go to get a refresher on all these things? 3) Or should I just be using ipcalc or an online calculator to do it all for me - and if so, which one?

• Wireless Repeating with two Netgear N750 (WNDR4300)

  - by jomo1911

  I have a Netgear N750 as my main router, which connects to the internet via a modem. I have a second Netgear N750 which I want to use to repeat the wireless signal of the main router. I logged in to routerlogin of my main router (192.168.1.1) and set up the "Wireless Repeating Function". I set it as the "Wireless Base Station" and filled in the MAC adress of my second Netgear N750. Then I logged in to routerlogin of my second router and set it up as the "Wireless Repeater", I gave it the IP 192.168.1.11 and filled in the MAC adress of the base station. During the setup of the second router (Repeater) I had to disable all security functions. If I connect to the repeaters' WLAN signal, I get no internet connection. Maybe you can help me, thanks

• Can't access an internal IIS web site via IP address, only hostname

  - by chris-untrod-com

  I have a machine on my home network running Windows Server 2008 (IIS7) with a web application running under default website called HTCOMNET. The network is just on a Windows Workgroup. The server is named nas1 and has a (dynamically assigned) IPv4 address of 192.168.2.12. I can ping 192.168.2.12. When I ping the machine by name ("nas1"), the hostname resolves to an IPv6 link-local address (as opposed to the ipv4 address). In a browser, I can go to http://nas1/HTCOMNET/ and IIS serves the site, no problem. But if I go to http://192.168.2.12/HTCOMNET, no dice. I have all the windows firewalls turned off. Any idea what's going on? I can't for the life of me figure out why I can't hit IIS via the IP. I feel like it's something really obvious, but i can't figure out what. Thanks!

• FortiGate firewall configuration with /30 and /28 networks

  - by slyderc

  I have fiber coming in from a new ISP which is being handed off via Ethernet on a single physical port. I'm having doubts about how to approach the configuration on my FortiGate 200A firewall because I've been given a /30 containing the ISP's gateway and another /28 for external IPs I can use: x.y.76.12/30 (.13 is the GW) x.y.76.64/28 (public IP space) How do I configure the FG200A's WAN1 interface to be aware of the two networks? As I only have one physical ISP port, will I need to plug it into a switch to break-out two cables and use a DMZ port on the FG200A for setting up the /28? Thanks in advance for your insight!

• QoS, Squid, Virgin superhub

  - by swiss196

  I'm a student and have just moved into a house of 6. We've setup 100mb broadband with Virgin and get quite good speeds on it so we're really pleased. However, as there are 6 of us, who all like to stream/game/download etc I was looking at setting up QoS to ensure speeds were fair/equal etc. I looked into it and found out that the Virgin Superhub can't do it out of the box, so my next option is to setup squid proxy on my machine (always on) to act as at transparent proxy and provide QoS etc. However, I'm not really sure how to do this and had a look on the Internet but couldn't see any guides as such! I was wondering if someone could give me some more and perhaps provider a summary of the steps involved - and let me know if this is possible with the SuperHub etc. Thanks, Dave

• internet connection drops randomly

  - by Remus Rigo

  hi all I have 3 PC's at home (with Win XP, Win 7 & Win 7) and a router. I am always connected to the internet through the router (PPoE connection). My problem is that sometimes when I want to search or open a page, my browser tells me that the server cannot be reached, as if I don't have a connection to the internet. Other times it logs me out from messenger, but browsing still works. FTP download/upload also works. If i disable and enable the LAN then all works fine. The connection doesn't always drop on all three PC's at the same time. Anyone got any idea besides re-installing OS? thanks

• How can I split 200Mbps of streaming traffic into routers?

  - by Jared

  As the title says, I have 200Mbps of streaming video traffic coming into my command center. How do I split the load between routers? Setup is like this: fiber --- router --- switch --- workstations I'm sorry I haven't dealt with this much traffic before. so please be gentle if you're going to kick me out :) EDITED FOR DETAILS: Okay, this specific project is for our company's IP CCTV system. We have deployed over 100++ cameras all over a building/campus and we have estimated each camera to take about 2Mbps of bandwidth each. Now, they're all connected to a switch and that's entirely fine. But coming into our command center, they have to be on a router since it'll get more than 200++ cameras next year (and I don't want to have too many hosts on one subnet). My plan was to have the 1st hundred on a 172.16.9.x block and the 2nd hundred on a 172.16.10.x block (all /24). The servers I have are currently sized to match (about 5 dual 6-core xeons) and I'd have about 19 workstations all streaming video from the 5 servers. (servers pull video from the cameras). But 200Mbps of constant traffic? How the hell do I even break this up? I need to have 1 gateway, to manage the routes... I honestly think I'm way in over my head.

• How to get gigabit network speeds on Windows XP?

  - by JB

  We've just installed gigabit switches at work, and things on the Linux side are going well. Our linux boxes, which use a Intel Corporation 82566DM-2 Gigabit nic (according to lspci), consistently get over 900 mbits/sec: iperf -c ipserver ------------------------------------------------------------ Client connecting to ipserver, TCP port 5001 TCP window size: 16.0 KByte (default) ------------------------------------------------------------ [ 3] local 192.168.40.9 port 39823 connected with 192.168.1.115 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 1.08 GBytes 929 Mbits/sec We have a bunch of Windows XP 64-bit machines that use Broadcom NetXtreme 57xx cards. I spent around a day trying to get equivalent speeds on them, but couldn't get above 200 Mbits/sec. I noticed the Windows iperf tests said that the TCP window size was 8 Kb by default (as opposed to 16 Kb on Linux, so I modified my test to reflect that. Still no love. I went to Broadcom's site, downloaded the latest drivers for the card and installed. Still no love. However, finally, I tried a 64 Kb window size with the new drivers, and finally an improvement! $ iperf -c ipserver -w64k ------------------------------------------------------------ Client connecting to ipserver, TCP port 5001 TCP window size: 64.0 KByte ------------------------------------------------------------ [ 3] local 192.168.40.214 port 1848 connected with 192.168.1.115 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 933 MBytes 782 Mbits/sec Much better, but still not really taking advantage of the full capabilities of the network. If the Linux box can reach 950 Mbits/sec consistently, this box should be able to as well. Also, if you're wondering about the medium, this is over the same cable...I'm switching back and forth. Any suggestion or ideas would be really welcome. Thanks!

• windows Home Server backup error

  - by domen

  I've finally built my WHS, but some other problems have showed up. I've googled, binged and searched SU with no success. The problem is following: at the moment I've got a Win7 laptop and Win7 PC, which should be backed up by the WHS. Laptop is backed up just fine with no issues, but when I try to manually backup the PC, after "backup is starting" message, when backup service should be monitoring changes on partitions, PC gets disconnected from the home network and thus, the backup process is stuck. Disabling/enabling network adapter gets PC back on the network. The only thing I've tried was reinstalling connector software. no success. Also, I've downloaded connector troubleshooter and only thing it says is "DHCP server was not found". I'm not good with networks, so I couldn't figure out what could that indicate (all computers in the network are assigned static IPs). Any ideas what the problem can be? I can provide any additional information, I'm just not sure what may be helpful right now. Thanks.

• Multiple access points for the same SSID ?

  - by krosenvold

  I need to upgrade my existing wireless infrastructure and this time I want 2 access points to cover my house, since I get blind spots no matter what with a single AP, I have physical cabling to my central network available for both access points. But I would really like these two to interoperate seamlessly as a single SSID. How do I do this and what are the features the new AP's I'm buying need to support ? (Product recommendations are welcome ;)

• What Wireless Router/ADSL Modem to get? N-band a must!!

  - by JJarava

  I'm looking for a Dual-N band Router OR ADSL Gateway and I'd like some recommendations. Situation: I have a 802.11b/g ADSL gateway provided by my telco, but the WIFI signal won't cover all the house (especially the living-room, so my tv-connected Mac Mini has poor to no internet access). So I'm looking to either replace the DSL modem with a N-enabled one, or to add a Router to the mix. I've had a modem+router setup for many years, and I know the advantatges (double NAT, double FW = more security) and issues (more complex to troubleshoot, two possible points of failure), so I'd rather live with a single (ADSL Gateway) device, if possible. Requirements: Dual-N Band (300 Mbs WIFI) 1 GB Ethernet ports ADSL2+ support (if it's a ADSL gateway, which would be desirable) "Best" range and speed possible Nice to have: USB port to share disks/printers on the network Media streaming I've been a long time user of Linksys, so googling around I found the WRT610N (http://www.linksysbycisco.com/US/en/products/WRT610N) for a "Pure Router" perspective, and it's one of those that Linksys styles "N++" (http://www.linksysbycisco.com/US/en/promo/Promotion-Go-Wireless?stepname=Promotion-Step-Go-Wireless-High-Performance) But I haven't been able to find similar "ADSL" gateways. I've found the WAG320N, but there is little to no info in the Linksys site (i.e., i don't know if it's Dual Band, or if it has GB ethernet) Any opinions/recommendations of other products/suggestions are more than welcome.

• Setting up 802.1X wireless connection on OSX

  - by hizki

  I am an OSX user, I have Snow Leopard 10.6.5 and an updated AirPort. I am trying to connect to my university's wireless network, but it has a complex security that I am having trouble defining... Here there are instructions for connecting with Windows XP, Windows 7 and Linux. Can someone please instruct me what should I do to set up this network on my MAC? Thank you. P.S. I have had previous success in setting up this network, but I have no idea what I did that made it work. Since I updated my AirPort it worked only seldomly and very slowly... Before the update, even when it worked it never remembered my password.

• Need assistance setting up Linux Router with 2 public lans

  - by user195407

  I was assigned a.b.c.10/30 (Public IP) for my router and given a.b.c.9 as the gateway. I was also assigned x.y.z.128/25 (Public IP block) for my use. I want to setup a Linux router to handle this situation. My Linux box has 3 NICs, eth0 is a.b.c.10, eth1 I have assigned x.y.z.254, eth2 is unused at present. I have eth1 connected to a network switch, and several devices connected. Let's say box A is x.y.z.129 with a gateway of x.y.z.254. I have not connected to the network yet, as it is not live. What settings do I need to make, beyond adding the 2 network definitions to the cards and having "route add default gw a.b.c.9 eth0"? I may add a private 192.168.100.0/24 lan to eth2 later.

• Upgrade AirPort on Macs to support Snow Leopard's Wake on Wireless/WLAN?

  - by wojo

  Snow Leopard now supports Wake on WLAN, but not all hardware supports this. For example, my Octo Mac Pro from early 2008 has an AirPort card, but it does not support this. Nor does my 2007 2.33GHz MacBook Pro. For reference to what is needed, look at http://www.macrumors.com/2009/08/28/a-closer-look-at-snow-leopards-wake-on-demand-feature/ which includes a screenshot of what the System Profiler should show. It's pretty hard to find Apple parts, but is it possible to put newer cards into these machines to have them support Wake on Wireless?

• SCM8014 to FVS338

  - by Jack

  I have a SMC8014 Router/Modem that Comcast provided me with their business class service. It was not filtering malicious traffic as aggressively as I had hoped, so I purchased a NetGear ProSafe FVS338, and put this behind the SMC8014, and all my machines behind that. After some brief configuration, all machines can see out to the internet. I also have a single web server, and I have not been able to configure things so that incoming requests can reach it. This is where I need help! I would like to have the FVS339 do NAT, so that I can assign a 192.168 address to my webserver. I've tried everything I know of, and I can't get things going. I set the SMC8014 to have a LAN facing IP of 10.0.0.1, and I assigned the FVS339 a WAN facing IP of 10.0.0.2. I would like to be able to tell the SMC8014 to just forward all traffic to 10.0.0.2, but I haven't had any success. In my (unfortunately limited) understanding, what I probably want here is a static route, but I don't know how to cofigure one, or if this is really what I want. The SMC8014 wants a Destination IP, a Subnet Mask and a Gateway IP. Any help would be appreciated.
