Awesome! Got pfSense 2.0 completely working on the ASUS 2G Surf!
Working with all three network interfaces, INCLUDING the ALFA AWUS036H!, with a NAT bridge configured from the ALFA to the Atheros wireless adapter! There were some weird glitchy type problems along the way. If anyone needs help with this in the future, send me a PM and I will be glad to help.
Much thanks to the devs for a kick butt distro! Among the best server side software I've ever used. That's including JBoss and Tomcat!
