If it would not be a great security risk, could you post the whole
set of ipfw rules that you are using?  Alternatively, could you add a
'log' clause to all the 'deny' rules, and then watch for denied packets
in the syslog?  As another alternative, you could 'ipfw -f' for the
duration of the test...

Sorry if I seem fixated on ipfw, but in my limited experience, it is the
single most common reason for jail network connectivity problems :)
Closely followed by missing /etc/resolv.conf files in jail/chroot
filesystems, but that's another story...

G'luck,
Peter
