Well, it was simply fustrating trying to find the "right NIC", I gave up after about 20 tries.
(Damn those companies for changing chipsets and not providing labelling for changes! How hard
is it to add a character to show that its a slightly different version?)
Anwyay, I went with a pair of Linksys WRT54G routers instead. I used HyperWRT (third-party firmware)
and was able to get both routers talking to each other with WPA-PSK (AES). Works pretty darn good.
(Interestingly, it supports RADIUS in this bridging mode as well).
Gonna be using pfSense for VPN end-points.
Thanks for your help.
Our friends at NetGate do not do this... http://www.netgate.com/
Everything is labelled and you get what you pay for. Check em' out.
NOTE: NetGate is a sponsor of pfSense, so they deserve your business!
