After reading this I feel that you have absolutely no packets on

contradicts with your previous assertion that if ICMP packet comes
in on rl1, then it is reflected at rl0. Am I missing something?
Yes I must mislook that, rl0 also is 'dead' while Linux box pings
my FreeBSD box using net on rl1.
OK, so I feel that there are two points to check.
1. Firewall. Even if you're running GENERIC, firewall thingies
are compiled as kernel modules and can be loaded by the startup
scripts. The output of 'kldstat -v' will show what modules
are loaded. BPF is run before filtering, so it sees packets
that firewall can drop.
2. Enable ICMP verbose mode in the kernel: set the variable
'icmpprintfs' on the top of the /sys/netinet/ip_icmp.c
to 1 and define ICMPPRINTFS during kernel compilation via
'makeoptions ICMPPRINTFS=1'. After this you should watch for
kernel messages with the 'icmp' at the beginning of the line.
Hope this helps.
