I am not sure what I did to break this box. It was working fine, before
I added the third network card (ne1) for the transparent bridge
for remote logging.
I was able to ping (and do other stuff) from the internal network
to the world. now I can only ping the world from the firewall.
Network traffic to the firewall is no problem. It just looks like
the thing does not forward anything.
and in /etc/sysctrl I do have
net.inet.ip.forwarding=1 # 1=Permit forwarding (routing) of packets
I also activated ipfiler and ipnat in rc.conf
netstat -rn
