You would need a setting in iptables?

Something to do with IP Masquerading

have a look at this;
https://help.ubuntu.com/9.04/serverguide/C/firewall.html

There's a section about IP Masquerading. It should help you fix your problem i think

Also, im running webmin, and it's easier to do masquerading via ssh.
