It's theoretically a proper bridge (a consumer grade bridge, so you never really know). It worked fine for two devices for a year, I've had guests' laptops plugged into it many times as a third device, with no problems. It's only the empeg traffic that's giving trouble. I've been thinking of replacing it with a newer setup anyway, so I've not worked on the problem a lot.
What I'd really like is a pair of wireless devices: One as a firewall and AP (with external VPN capability so I can listen to my home, docked empeg from work), and the other as a wireless bridge and AP (to give me better coverage on my deck out back). WPA2 and a/b/g (or just a and g). I'm just starting my hunt, though.
