You are going to have to use something like "redir" or "ipmasqadm" to forward
traffic to that host.  As it sits on your private network you are going to
have to put the port redirection in place on your linux box with the eth0
address of 1.2.3.5.  Take a look at how "redir" can take incoming packets and
forward them to machines sitting behind the firewall on a private subnet.

See ya
