Newbie request - a small clarification

[Nandan Bhat]

Hi Rob, Pascal, Anisha:

I am sorry for not presenting the complete picture earlier.

(Recap)
192.168.1.6/255.255.255.0 (static) on eth0
192.168.0.0/24 by DHCP on eth1

I need to have mail to/from 192.168.0.10 from 192.168.1.0/24 network.

I forgot to mention that mail is already setup on 192.168.1.6 using
ports 25/110 .

Will it work to proxy on say 25000/11000 by using "-m mport -p tcp
--sports 25000,11000" in addition to the --dports 25,110?
