Im trying to do something trivial here, but I just cant seem to figure out
whats going on. Im trying to build a gateway that only accepts ESP tunnel
packets. When I enable firewall rules something like:
/sbin/ipfw add allow udp from any to any isakmp via xl0
/sbin/ipfw add allow esp from any to any via xl0
/sbin/ipfw add deny all from any to any via xl0
/sbin/ipfw add allow all from any to any
Communications fails. The thing is, I cant figure out why.
I have xl0 internetaddressed, and dc0 internal network addressed, with a gif0
tunnel setup for the ipsec tunneling. Suggestions?
Thanks!
