Hello,

This patch removes ipfw1 in favour of ipfw2. ipfw2 is a superset of ipfw1 and no functionality should be lost. This will make bringing in improvements to ipfw2 from FreeBSD easier. This includes a PFIL_HOOKS conversion and additional functionality.

After applying the patch you must rebuild world and kernel. [ Or at least kernel, sbin/ipfw and lib/libalias are recompiled and reinstalled. ]

Regards

Gary
