P2P T1 Design Help

[abruso]

We have two sites that is currently connected VIA a PIX-to-PIX IPsec VPN tunnel so that we can transfer data back and forth. The transmission rate is too slow for our needs though so we recently purchased a dedicated T1. My question is will our current hardware/configuration be able to work with a T1 connection or will we need to buy new hardware?

Here is our current hardware layout:

SITE1 - PIX515 - ROUTER --------- ROUTER - PIX515 - SITE2

Both routers are Cisco as well and both have an available WIC-1DSU-T1 card in them.

Both routers have 3 interfaces; 2 ethernet, and 1 serial (WIC-1DSU-T1). The outside interface connects to the ISP, the inside interface connects to a switch, which then connects to the outside interface of the PIX. The serial interfaces are not being used yet. This is true for both routers.

So I guess my concerns are will this T1 connection work with our current routers and IP layout? If you need to see the router configs for the twow sites to get an idea of the IP structure let me know and I will post them.

Thanks for any help.

It should work fine, this is a very common configuration.

Good Luck

Ok, so I'm still a little confused.

On site 1, the perimeter router uses an IP range given to us from our ISP. (x.x.224.81-95).

On site 2, the perimeter router uses an IP range given to us from a different ISP. (x.x.202.82-95)

When I set up the serial interface on these routers I need to use my own private IP address right?

The inside subnet of our network behind the PIX at site 1 is 10.0.0.x, and the inside subnet of our network behind the PIX at site 2 is 192.168.1.x.

So my question still remains. How do I configure the serial interfaces on the routers to allow workstations and servers on the 10.0.0.x ip space in site 1 to talk to servers in the 192.168.1.x ip space in site 2? Thanks.
