I have two internet connections, a LAN and a 3G modem on a Windows 7 machine.

The LAN is connected to a Edimax router which is conneted to the ISP (with their own modem).

Now, the Edimax router is set to auto assign IP adresses in the range: and

I wanted to block Internet Explorer to access the LAN.

I entered my AVG firewall, selected IE and added a "block" rule which blocked all ports, TCP and UDP protocols for the above IP range. The problem is it did not work, not matter what rules I have tried.

How can I accomplish this?

Windows 7 has a load balancing system and it prefers the LAN first followed by the 3G connection. What I want to to block IE in using the LAN so Win 7 will be forced to make IE use the 3G. Your comment does not make sense – webmasters Nov 29 '12 at 5:34
