I had the same problem until I was told to add 'out
xmit' to my config. You may want to change your line
to:
${fwcmd} add pipe 1 tcp from 192.168.0.0/24 to any out
xmit dc0
This should inform ipfw to parse the rule only once.

If the proposed change isn't a valid ipfw-syntax, you
have to upgrade to ipfw2 which is the default in
FreeBSD 5.x, whereas FreeBSD 4.x defaults to ipfw ver.
1. Read the man-page for ipfw on how to upgrade.
There is probably a different approach staying with
ipfw ver. 1, but I'm unaware of that.
