  • What happened to my "Predefined rules" in Windows Firewall? How can I get them back?

    - by Cheeso
    Windows Firewall Advanced Settings in Windows 7 , has predefined rule sets. When I click the "Add Rule..." button in my Windows 7 Ultimate install, it looks like this: But, on a machine I have that runs Windows 7 Home Premium, when I click "Add Rule...", the "predefined rules" option is greyed out. Like this: Is this expected? Does Win7 Home Premium NOT have predefined rules? How can I get the rules back?

  • What anti-virus & firewall (with IDS) should I use for a windows server machine?

    - by Eran Betzalel
    I want one product to cover for Anti-virus & Firewall purposes. The product should also be lightweight and of course designed for windows server. Any suggestions? Note: I don't need an enterprise solution for the clients - only for the server. BTW, I currently using Symantec SEP, but it's too heavy (during weekly scans) for the server to handle and is not designed for server purposes.

  • How does Azureus get my firewall to open a port (Debian Linux)?

    - by Norman Ramsey
    I downloaded Azureus (a bittorrent client) for Debian Linux, and I notice that Azureus got my firewall (a Verizon wireless base station) to open a TCP and UDP port forwarding for it, without my having to do anything. My base station is password protected, and I'm alarmed at the idea that any random application can open ports without my knowing about it. Can somebody explain to me what is going on and how it is possible that Azureus can create this port-forwarding rule without any authentication?

  • What is the best Web Application Firewall for IIS?

    - by user30850
    What is the best Web Application Firewall(WAF) for IIS? What makes it better than the others? How useful is it at blocking attacks against poorly written code, otherwise known as an Intrusion Prevention System (IPS)? WAFs are required by the PCI-DSS, so if I have to get one, then it should the best one.

  • Windows XP Firewall : Allow all incoming traffic from local subnet.

    - by Martin
    I have some Windows XP machines that are using the standard Firewall to control traffic. I have a need to allow all incoming traffic on all ports from the local subnet (255.255.255.0). I have looked at the settings and it would appear that I can indeed set scope for a rule, but a rule is applied only against an application or a single port. Is there a method to do this?

  • Do newer physical interfaces make a better linux firewall?

    - by pfyon
    At work we use an old (10 year old) linux box with 4 interfaces to act as router/firewall for the network. There's never really been a need to change it since it's stable and handles all our needs. I'm wondering, though, would replacing the network interfaces with newer ones provide a benefit? Besides the obvious bandwidth increase (eg. 100MBit to GBit), would there be a latency reduction, or do newer cards pretty much do the same thing as old ones?

  • Any problems usinga GoDaddy SSL certificate on a Cisco ASA firewall?

    - by Richard West
    I need to purchase and install a SSL certificate on my Cisco ASA firewall. This will allow my VPN users to connect to my ASA without receiving the certificate error from the untrusted self assigned SSL certificate that is currently on the ASA. I had good experiences with the SSL certificates that GoDaddy sells. However, I'm concerned about using them. On my web servers I have to also install GoDaddy's "intermediate certificate bundle". On the ASA I do not think that I will be able to preform anything like this. I do not fully understand what the "intermediate certificate bundle" does, but obviously it's important. So my question is can I use a GoDaddy SSL certificate on an ASA without my users getting any type of warning or error about connecting to a site that using an untrusted SSL certificate. I need this to be as simple as possible for my end users and warning messages are always scary :) Thanks!

  • Changing default gateway on workstations connected to Windows Domain SBS server

    - by Gary B2312321321
    We have xp workstations connected onto a small business server acting as active directory/isa firewall/proxy (no dhcp). Is there a reason that after installing a 2nd firewall on the network (same subnet etc), that changing the default gateway on the workstations isnt sufficient to route inet traffic through the new firewall? A freshly setup linux box connects straight on to the alternate firewall with just ip, default gateway. dns settings. Will having ISA still active on the network confuse the process? Are there further config settings deeper down in windows that need attention? Any ideas pointers on this would be appreciated? Other info: Firewalls tried: Smoothwall and Ipcop; small ethernet netwoork 40 pcs; can ping to new firwalls from workstations; activating web proxy on new firewall and reconfiguring workstation browser works fine; Point of 2nd firewall is lack of some necessary features on ISA for a linux app; Would be nice to have some redundancy to though

  • How to enable connection security for WMI firewall rules when using VAMT 2.0?

    - by Ondrej Tucny
    I want to use VAMT 2.0 to install product keys and active software in remote machines. Everything works fine as long as the ASync-In, DCOM-In, and WMI-In Windows Firewall rules are enabled and the action is set to Allow the connection. However, when I try using Allow the connection if it is secure (regardless of the connection security option chosen) VAMT won't connect to the remote machine. I tried using wbemtest and the error always is “The RPC server is unavailable”, error code 0x800706ba. How do I setup at least some level of connection security for remote WMI access for VAMT to work? I googled for correct VAMT setup, read the Volume Activation 2.0 Step-by-Step guide, but no luck finding anything about connection security.

  • What is the best way to bypass China firewall to allow SSH deploy@**.com

    - by Lap
    I am trying to bypass the china firewall and allow SSH deploy@**.com at the command console. This is because I need to test the games I wrote on apps.facebook.com/**. I tried VPN (both pptp and openvpn), but they aren't that great as connection speed slows down significantly. Since I am deploying the game in another site, my browser needs to download the game, which is super slow. What are ways of bypassing the firewall other than getting a VPN? I was thinking maybe have a computer outside China and using teamviewer to access...

  • Something in the world of Firewall Hosted SSL VPN's

    - by AreYouSerious
    I run a Physical firewall at my residence. Call me paranoid, but I appreciate the added security. I have been working to get the VPN to work properly, but had until today not managed this. I worked with ensuring that the VPN configurations were correct, that the port filters were correct,  I could connect to the Firewall GUI, but never to the VPN. Turns out that in W7, if you add a key, it suddenly works.Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNELAdd DWORD(32-bit) - SendExtraRecord --> value 2 and voila, suddenly your presented with the login screen. I won't mention the specific vendor, as they don't have this listed in their fixes... but there are several venders where this is an issue. So, if you are having an issue connecting to an SSL VPN (web vpn) this might just be the solution that you need.

  • Sending emails with remote mail server in ASP.NET blocked by Windows firewall?

    - by Dave
    I want to migrate a web application from a Windows Server 2003 to a Windows Server 2008 R2. All works fine except sending emails from the application. If I configure the application to use the smtp server on "localhost" it works, but changing it to the "real" host name (e.g. mail.example.org) no mail is sent. The error message says, that the remote server needs a secure connection or smtp authentication. But since it works when using "localhost" instead of the host name I doubt that this is the problem. Also it's unlikely a problem with the mail server, I also tried it with another one. So for me it seems like the firewall is blocking the outgoing connection to the mail server. I tried to open port 25, but it still did not work. Maybe I just did it the wrong way.

  • Aus 2 mach 1: Oracle Audit Vault and Database Firewall

    - by Heinz-Wilhelm Fabry (DBA Community)
    Gestern hat Oracle bekanntgegeben, dass die beiden Produkte Oracle Audit Vault und Oracle Database Firewall zu einem Produkt werden. Der neue Produktname wird "Oracle Audit Vault and Database Firewall" sein. Software und Dokumentation werden in den nächsten Tagen zum Download verfügbar sein. Das Zusammenlegen macht durchaus Sinn, denn die ursprünglichen Produkte wiesen im Bereich der Protokollierung und des Berichtswesens deutliche Überschneidungen auf. Damit lag es nahe, die Repositories für das Speichern des Protokolls zu vereinheitlichen. Endlich wird es im Bereich Auditing durch die Einführung eines Development Kits auch möglich sein, Systeme anzubinden, für die Oracle keine vorgefertigten Konnektoren / Kollektoren liefert. Mit der Zusammenlegung verbunden ist ein völlig neues Lizenzierungsmodell, das zu deutlichen Kostensenkungen für kleinere und mittlere Installationen führt.

  • How to SSH an outside server from a computer which is behind a proxy firewall ?

    - by Karan
    I access the Internet through an HTTP proxy firewall at college. And I need to login to a computer, via SSH, which is outside our network. I tried it as Linux command and on Windows using PuTTY. I also configured PuTTY to use our server's address. But still, "Proxy error: 403 forbidden" pops up. They must've blocked SSH access to outside systems. (college systems as accessible). I can SSH a web server (not the proxy server) at the college, which I use to browse proxy-free by tunneling. Now this server allows to browse restricted sites, but still no SSH. Any workaround, please?

  • Windows 2008 Server Firewall blocks from printing in other subnet

    - by xenolf
    Greetings, i have a windows 2008 server with activated firewall in the 192.168.0.xx subnet. From there i want to print on an printer which is located in the 192.168.10.xx subnet. Now when i try to print with the firewall on, nothing happens... when i turn the firewall off it prints flawlessly. Now i messed around with the windows firewall for about 4 hours straight and i cant seem to find a rule which lets me print. Even when i set the firewall to let everything through im unable to print. Has anyone encountered the same or a similar problem and has a solution for this issue? Thanks in advance xenolf

  • Why would http & https be blocked, even in safe mode with firewall disabled?

    - by Cogwheel
    I have a windows 7 machine (dell studio xps). Everything on it seems to be in working order. The network device says it has internet connectivity, and indeed I can ping websites, transfer files via ftp, connect to vpns and remote desktop, but the web won't work. I've disabled the windows firewall and still no go. There are no other firewalls installed. The computer came with a trial of norton 360 so I also used the norton removal tool (which solved a similar problem on another computer for me previously). Any thoughts?

  • Lots of strange IP addresses in my Windows Firewall logs. Concern?

    - by gmoore
    Was trying to debug a Samba sharing issue with Mac OS X so I turned on logging for my Windows Firewall. I didn't expect a lot of conections but the thing filled up quickly. Here's a sample: 2009-12-21 08:49:32 OPEN-INBOUND TCP 192.168.0.4 192.168.0.3 56335 139 - - - - - - - - - 2009-12-21 08:49:33 OPEN-INBOUND TCP 192.168.0.4 192.168.0.3 56337 139 - - - - - - - - - 2009-12-21 08:50:02 OPEN UDP 192.168.0.3 68.87.73.242 1389 53 - - - - - - - - - 2009-12-21 08:50:02 CLOSE TCP 192.168.0.3 212.96.161.238 1391 80 - - - - - - - - - 2009-12-21 08:50:02 OPEN UDP 192.168.0.3 68.87.71.226 60290 53 - - - - - - - - - 2009-12-21 08:50:02 OPEN TCP 192.168.0.3 212.96.161.238 1391 80 - - - - - - - - - 2009-12-21 08:50:02 OPEN TCP 192.168.0.3 212.96.161.238 1393 80 - - - - - - - - - 2009-12-21 08:50:04 CLOSE TCP 192.168.0.3 212.96.161.238 1393 80 - - - - - - - - - 2009-12-21 08:50:41 CLOSE UDP 192.168.0.3 192.168.0.4 137 50300 - - - - - - - - - I can pick out the local IP addresses (192.168.0.3 is my Windows XP machine, 192.169.0.4 is Mac OS X) as I debug the Samba issue. But some of the others resolve to Comcast (my ISP) and others resolve to weird hosts like van-dns.com and navisite.net. It doesn't look like any connection sent/received any bytes. I used the reference here: http://technet.microsoft.com/en-us/library/cc758040%28WS.10%29.aspx. Is it a cause for concern?

  • What is the ip range of EC2

    - by Nicolas Kassis
    I'd like to setup a rule to block ssh request from EC2 since I've been seeing a large amount of ssh based attack from there and was wondering if anyone knew what their IP ranges are. EDIT: Thank you for the answer, I went ahead and implemented the iptables rules as follow. I ignore all traffic for the moment. Logging it just to see if the rules are working and for stats on how much crap EC2 is sending out ;) #EC2 Blacklist $IPTBLS -A INPUT -s 67.202.0.0/18 -j LOG --log-prefix "<firewall> EC2 traffic " $IPTBLS -A INPUT -s 67.202.0.0/18 -j DROP $IPTBLS -A INPUT -s 72.44.32.0/19 -j LOG --log-prefix "<firewall> EC2 traffic " $IPTBLS -A INPUT -s 72.44.32.0/19 -j DROP $IPTBLS -A INPUT -s 75.101.128.0/17 -j LOG --log-prefix "<firewall> EC2 traffic " $IPTBLS -A INPUT -s 75.101.128.0/17 -j DROP $IPTBLS -A INPUT -s 174.129.0.0/16 -j LOG --log-prefix "<firewall> EC2 traffic " $IPTBLS -A INPUT -s 174.129.0.0/16 -j DROP $IPTBLS -A INPUT -s 204.236.192.0/18 -j LOG --log-prefix "<firewall> EC2 traffic " $IPTBLS -A INPUT -s 204.236.192.0/18 -j DROP $IPTBLS -A INPUT -s 204.236.224.0/19 -j LOG --log-prefix "<firewall> EC2 traffic " $IPTBLS -A INPUT -s 204.236.224.0/19 -j DROP $IPTBLS -A INPUT -s 79.125.0.0/17 -j LOG --log-prefix "<firewall> EC2 traffic " $IPTBLS -A INPUT -s 79.125.0.0/17 -j DROP

  • Can not open ports in iptables on CentOS 5??

    - by abszero
    I am trying to open up ports in CentOS's firewall and am having a terrible go at it. I have followed the "HowTo" here: http://wiki.centos.org/HowTos/Network/IPTables as well as a few other places on the Net but I still can't get the bloody thing to work. Basically I wanted to get two things working: VNC and Apache over the internal network. The problem is that the firewall is blocking all attempts to connect to these services. Now if I issue service iptables stop and then try to access the server via VNC or hit the webserver everything works as expected. However the moment I turn iptables back on all of my access is blocked. Below is a truncated version of my iptables file as it appears in vi -A RH-Firewall-1-INPUT -p tcp -m state --state NEW -m tcp --dport 5801 -j ACCEPT -A RH-Firewall-1-INPUT -p tcp -m state --state NEW -m tcp --dport 5901 -j ACCEPT -A RH-Firewall-1-INPUT -p tcp -m state --state NEW -m tcp --dport 6001 -j ACCEPT -A RH-Firewall-1-INPUT -p tcp -m state --state NEW -m tcp --dport 5900 -j ACCEPT -A RH-Firewall-1-INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT Really I would just be happy if I could get port 80 opened up for Apache since I can do most stuff via putty but if I could figure out VNC as well that would be cool. As far as VNC goes there is just a single/user desktop that I am trying to connect to via: [ipaddress]:1 Any help would be greatly appreciated!
