Hi Orson,

Unfortunately, Apache is listening to 80 -- I think I know that
because the webserver is accessible from inside the LAN.  But just to
make 100% sure,

root@satan:/etc/network# netstat -tapn | grep -i listen | grep -i :80
tcp     0     0*            LISTEN      14090/apache2

I think the same argument applies to the firewall idea.  Using
tcpdump, I can definitely see external packets arrive at the right
computer at the right port.  I also checked tcpwrappers, and put ALL:
ALL in hosts.allow, but that didn't work.  It seems like everything
points to Apache not knowing to look at incoming packets that
originated outside the LAN.

iptables has no rules in it, unfortunately.

Great suggestions!  Thank you!
