>My bad, I didn't realize you couldn't bridge this way. I have the reverse setup going in my room, wire from gateway to BSD box which provides an additional access point to other wireless devices in my room. I know it doesn't meet your original requirements but you could set up your openbsd box to host a second LAN off of re0 and then nat-to its address on the wireless. Or just set up a second network and configure your routing tables approriately and you shouldn't need NAT.
