Hi all -

I just recompiled the kernel on my gateway with the 
ipfw options enabled (I'm still at 2.1.7).

It seems to work fine, with the minor exception that my local
LAN can no longer see the the gateway or the rest of the world...

I suspected, of course, my ruleset at first. But flushing the
rules and adding

ipfw add allow all from any to any

doesn't alter this behavior. If I drop back the the kernel without the IPFW
options, everything is fine.

Aynone have a clue what's going on?

Thanks.
