Here's the setup

I have a Verizon router in the basement connected to the Internet. It's internal ip is 192.168.1.1

There are two routers connected to it. One is a VOIP router/adapter used to power the building phone system VOIP. It's network addy is 192.168.3.1 The other router is a Linux box 192.168.2.1 and the main home network runs as a subnet off that router which also provides network services and other things. I can connect from any machine on the subnet 192.168.2 to the VZ router 192.168.1. But I cannot make any kind of connection between the subnets 192.168.2 and 192.168.3 What would it take to enable packets to be sent directly from a machine one subnet to the other ? What if I just use a bridge ? Can a network bridge connect my two subnets without having to go thorough some crazy forwarding scheme on the VZ router? Where would the bridge go ?

why have the VoIP adapter route at all? just stick it on the existing network and let it get an address there.

also, you can turn your linux box into a router by sticking a 2nd interface into it and having it be the default gateway for both networks.

Easy fix, do it the same way I did.
I put the Vonage VOIP router on it's own network off of my main router. It is its own network and if I need to "talk" to it I just use the admin addy (example 192.168.2.1:8080) and it thinks I'm getting to it from the Internet when in reality its protected from the web and won't affect my network.

Just set all of your netmasks to 255.255.0.0 and it will all be one big subnet.

Problem solved.

Hmmmm....might just work at that. I'll try.
