Turn on tcpdump on the outer interface and watch the pings, # tcpdump -i <oif> icmp If you see the pings going out to the correct IP and nothing or screwed up packets are coming back, it's a problem on the Sun. If you see the correct pings coming back, something's wrong with the FreeBSD machine. Send the output you get from the above if you cannot figure it out. -- Crist J.
