	How about RIP?  I recently tried to upgrade my FreeBSD 4.0 
bridging-firewall to CURRENT and I could no longer get RIP packets through 
(reliably) (even with no rules and "DEFAULT_TOACCEPT") and had all kinds of 
routing problems...  Routers could not learn the route out because RIP was
not going through.  Of course I backed back off to 4.0-RELEASE and life was 
good again...  I sent in a PR but have not heard anything yet.

Advice?

Thanks
