Some other possibilities (I think I had the second one on my cable setup) are 255.255.255.126 255.255.255.124 255.255.255.120 255.255.255.112 255.255.255.96 255.255.255.64 Getting the wrong one is still likely to work fine, because you'll never be talking to another machine on the same subnet anyway. Remember that *inside* the firewall you have a different subnet--this is only for the Airport. Mike
