[plug] Routing

[Jonathon Bates]

Hi guys,
Just curious as I have never done this before.
Say I have a box acting as a gateway. In that gateway (well within the
gateways network) I have a block of live IP's that all need access to the
world (easy)  and each machine needs to be accessed from outside that
network. How do I go about allowing traffic to flow freely in and out?

Is it simply a firewall issue or something else?

Cheers
