I'd already played with one_pass without luck, and have tried again. # sysctl -a net.inet.ip.fw.one_pass net.inet.ip.fw.one_pass: 0 #ipfw show .. 00420 4942806 6549461073 pipe 420 tcp from IP 80 to any 00440 0 0 pipe 440 tcp from IP 80 to any .. I tried removing both rules and pipes, adding them back, it hasn't helped. -- Kelsey Cummings - kgc@sonic.net sonic.net, inc.
