State-Changed-From-To: open->closed
State-Changed-By: keramida
State-Changed-When: Thu May 11 17:57:13 UTC 2006
State-Changed-Why: 
The IPFW2 stuff has been changed in RELENG_5 and removed altogether
from RELENG_6 and HEAD.  No need to keep this PR open just for the
RELENG_4 branch, which is close to EOL now.
