If you compile in ipautofw masquerade support, you can use the kernel
to forward the traffic from one port to a port on a machine behind
the firewall. To the firewalled machine, the connection appears
as if it comes from the actual system connecting, not the firewall,
so the address is correct.
You will need to get the ipautofw program in order to configure
this. You can find a copy at ftp://ftp.netis.com/pub/members/rlynch/.
