Getting closer ...
123.456.70.66 is my host computer where firewall is being tested. ping 246.8.161.244 - works. However, traceroute 246.8.161.244 fails / hangs with this repeated error message in /var/log/ipmonlog: 03/07/2007 15:07:35.071265 eri0 @0:53 b 123.456.68.1 -> 123.456.70.66 PR icmp len 20 56 icmp timxceed/transit for 123.456.70.66,52646 - 246.8.161.244,33434 PR udp len 20 40 IN From the ipfstat below I (think that I) explicitly allow: 1) TCP & UDP access from 123.456.68.1, my subnet gateway (@18, @19). 2) ICMP access from anywhere (@52). So, again, what am I missing?
