This weekend I built the whole generic-cdrom branch from scratch, enabling IPSTEALTH option in the
new kernel. Then placed sysctl.conf in /etc with the line "net.inet.ip.stealth=1" inside it, but
with no luck. TTL of packets passing through the m0n0wall still decrements. Any ideas how to enable
it. 
I had some problems in the past with my ISP sending every single packet to me with TTL=0, so I want
to reinsure myself if something like this happens again. Thank you in advance. :)
