I have configured a machine with 2 NIC and IPFW in a rather simplistic
way as we are using it to emulate different link characteristics rather
than as an actual firewall.
00100 4 355 pipe 1 ip from any to any via de0
in
00200 1 56 pipe 2 ip from any to any via de0
out
00300 0 0 pipe 3 ip from any to any via de1
in
00400 3 288 pipe 4 ip from any to any via de1
out
65535 4 246 deny ip from any to
any
The configuration works fine and traffic crosses the firewall without
problem, except ICMP packets having timestamp or routing option, and
these are not returned.
Is there a way to allow these packets to enter/exit the firewall?
Regards
Malcolm
