need iptables rules

frieza · 08-28-2012, 03:48 PM

just a little project i'm working on
i have the following setup

Code:

workstation(ham0) - / - (ham0)home unit(eth0)--(lan sw)router(wan port)--dsl modem

interface ham0 is a hamachi network
the router is a linksys running dd-wrt micro build+ssh
the modem is a d-link adsl modem

what i would like to do is say forward port 81 to port 80 on the router and port 82 to port 80 on the modem (from interface ham0) so i can access the modem/router's setup pages from any workstation on the hamachi network

supposedly i can do this with iptables but i'm not up to par on doing this

any help would be appreciated

This sounds like a major security risk. I would advise against it as it's no different than opening up remote administration to the public domain. Even worse if the forwarding you're attemting to do is on the internal port you're severely exposing your internal network to the public domain.

Forwarding ports with iptables is easy enough with a google search however, again, I advise against it.
