What I'd like to do is to force an instance of a browser to use a specific Network Interface. I've tried: http://www.r1ch.net/stuff/forcebindip/ and was less than successful - besides, I'd like to have an instance of the browser using the other interface.
What I've been doing is firing up a Virtual Box and setting it to use the wireless network interface while the rest of the computer uses the wired network interface. This works great, except I don't want the overhead of having a VM running. I'm using this to test firewall settings, etc from an outside connection.
Any other suggestions?
