establishing tcp stream causes system to reboot when ipfw fwd rule is used to select the output interface. How-To-Repeat: configure two nodes on one lan as follows : node01 ifconfig em1 alias 10.77.1.2/24 ifconfig em1 alias 10.77.2.2/24 ipfw add 101 fwd 10.77.1.1 ip from 10.77.1.2 to any out ipfw add 102 fwd 10.77.2.1 ip from 10.77.2.2 to any out node02 ifconfig em1 alias 10.77.1.1/24 ifconfig em1 alias 10.77.2.1/24 In one window on node01 run "nc -l 8889 > /dev/null". In a second window on node01 run "yes | nc -s 10.77.1.2 10.77.2.2 8889". The system freezes then reboots. Remember to enable IPFIRWALL_FORWARD in the kernel.
