Re: Forward 2 networks

["Dave Piscitello" <dave () corecom com>]

This is the wrong forum - your question is about routing - but I 
believe I can answer for you.

Based on what you say, I believe you have two subnets:

192.168.2.0/24
192.168.3/24

The default gateway for 192.168.2.0/24 is 192.168.2.1, which I assume 
is your access to the Internet.

Hosts on your network 192.168.3.0/24 can forward traffic to 
192.168.3.7 as the gateway to 192.168.2.0/24 and, more generally, as 
the default gateway to any network/Internet.

You must enable routing on the PC joining the two networks.

The other half of the routing solution is that you must tell your 
current default gateway 192.168.2.1 that a network 192.168.3.0/24 is 
reachable via 192.168.2.7.

You can accomplish this easily with static routes at your dual-
connected PC and 192.168.2.1. You could enable a routing protocol at 
the PC and 192.168.2.1 but that is probably overkill.
