The very first screen opens HTTP (80) to the example host
192.168.1.25.  Other than that, you need to make sure the system on
the LAN is using m0n0wall as its default gateway and that it actually
has the port open.

You sure you want port 47?  I'd never seen that in use, looking it up
in /etc/services shows it's for something called "ni-ftp" (note that
isn't typical FTP).
