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

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?
