>Description:
After executing the following firewall ruleset the system gets a kernel panic.

ipfw -f flush
ipfw -f pipe flush
ipfw add 1 pipe 1 ip from 192.168.0.0:255.255.255.0 to 0.0.0.0/0
ipfw add 1 pipe 1 ip from 0.0.0.0/0 to 192.168.0.0:255.255.255.0
ipfw pipe 1 config bw 204Kbit/s

>How-To-Repeat:
Execute the above rule set with bridging+ipfw+dummynet enabled on FreeBSD 4.1.1 and start to transfer data acrost the bridge
>Fix:
I know this doesn't happen on 4.0-R.
