"Hide Source IP" / Hide Incoming IP"

[bdsnyder]

I want to port forward to an internal server that does NOT
have pfSense as its default gateway.

I have done this using GNAT-box's feature call "Hide Source",
and have used, for example:

iptables -t nat -A POSTROUTING -s 0.0.0.0/0 -o eth1 -j SNAT –to-source 192.168.1.1

on other linux (centos) boxes I have used as a router...

I do not want to have to change any settings on the internal server(s)...

I've read and searched this forum, but did not see a solution to this here.

Thanks for any suggestions !!!
