m0n0wall (LAN) is 10.0.40.1 (/24)
server at 10.0.40.3
PC at 10.0.40.21
Added alias ('ifconfig em0 inet 10.0.10.2 netmask 255.255.255.255
alias' on FreeBSD) on the server in question.
Added static route to m0n0wall, on LAN interface, pointing
10.0.10.2/32 to 10.0.40.3.
With Ethereal going, tried to ping 10.0.10.2 from 10.0.40.21. First
ping went through, routed by m0n0wall, ICMP redirect was sent from
m0n0wall, subsequent pings went through without touching m0n0wall. I
could hit http://10.0.10.2, ssh to 10.0.10.2, etc. Everything I tried
One thing I just thought of was that these services aren't strictly
bound to the 10.0.10.2 IP, they're bound to all IP's. Regardless,
that shouldn't matter.

Yeah I didn't see any ICMP redirects either in your tcpdumps. With
that static route added, go to exec.php and run a 'route print
126.96.36.199/32' (replaced with the IP of the route) and see what comes
You're using 1.2b7, I reverted my production box back to b3. One
other difference is you're using OPT, I'm using LAN. I'm curious if
you try a pre-5.3 version if it works as intended. I'll see if I can
try a b7 test box, and try an OPT interface.

What's 'ping -l' on Linux? (out of curiosity) That's for preload on
FreeBSD, so that command isn't syntactically valid.
