So here's a fun one for you.

Lately, I've been running dual gigabit NICs off my mobo, and one goes directly to a Time Warner Business 10/10 connection with a static IP. This one is used exclusively for hosting servers out of my main computer.

The second one goes to a Linksys WRT54GSv7 running DD-WRT v24. This, obviously, is for LAN use.

The LAN connection's metric is set to 1, the WAN to 2, so all traffic goes out over the LAN except for the server traffic, which is specifically requested out over the WAN port anyways.

I've been hunting for firewall software that'll allow me to disallow all traffic EXCEPT a few specific bits of software to the WAN port and still allow the LAN port to function normally. I've tried Windows Firewall, Symantec Endpoint Security, Kaspersky IS, Trend Micro business, McAfee Enterprise, everything I can think of (that is x64 native, that is - I'm running Vista Ultimate x64 on my desktop at the moment and I don't want to rebuild to Server 2003 x64 SP2).

Anyone seen anything like this?
Signature file is under revision. This will be back shortly.
