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?

    Set up a loopback adapter to your wireless (bridged) then setup a proxy to use that loop back adapter, and set your browser to use that proxy... – Piotr Kula Jan 23 '12 at 15:14
  • what is the reasoning behind going out one or the other eth? Typically systems have route tables, but not based on software like browsers, but on route to host. – Jakub Jan 23 '12 at 15:37
  • @Jakub just to get an external IP. In this instance, I'm tethering my phone - which is outside of the firewall while the rest of the computer is inside the firewall. – Some Free Mason Jan 23 '12 at 15:59

An option would be to use a (temp) route in your OS that points to the address of the website. The route would need to have a lower metric than the default gateway.
