If you don't need actual WAN interfaces, just something that introduces
delay / jitter / drops / bw-limiting like a WAN, I've had a lot of success
with BSD's dummynet.  Bridge two Ethernet interfaces together, and use
ipfw to introduce all kinds of interesting WAN-like behaviours.

http://www.scalabledesign.com/articles/dummynet.html was a useful intro.
