How to modify AVG Firewall settings

      Comments Off on How to modify AVG Firewall settings

This article was written specifically for our clients that use AVG CloudCare managed virus protection which has a firewall built in.  As of this article, we can not remotely managed your firewall settings, but we can remotely manage everything else.  You may find that if you have network connectivity problems you may have to allow traffic through your firewall.  Generally, you can block outside traffic but still allow your local network full access for network printers, servers, etc.  Here’s the detailed instructions how to set/modify your firewall and whitelist your network.

Launch Command PromptFirst thing you need to do is open a command prompt which you can get by right clicking your start button in Windows 8 or 10 and selecting Command Prompt.  In Windows 7 simply left click the start menu and type in cmd and press enter.

When in the command prompt, type ipconfig and press enter.  You’ll see a bunch of information which you may have to scroll up to find it if it scrolled too far down.  You are looking for IP address, Subnet Mask and Default Gateway.  If you see the Default Gateway as in the image below is 192.168.13.1 you will need to remember this number.  You can write it down and close the command prompt.

In the next Window that appears, you want to click Add IP, then another Window pops up where you can type in IP address range.  This is where you need to remember the Default Gateway you wrote down earlier of 192.168.13.1 or in the screen shot below 192.168.0.1.  Whatever your number was for Default Gateway, write it in the From field.  Write the same number in the To field with the exception of the last octet being 255 instead of 1.

Now click OK, OK, OK and then x out of the AVG interface.  You’re done.
