Dedicated Circuit to business partner

[ekinike]

I was recently informed that we require a dedicated point-to-point T1 circuit with a business partner. They are handling the circuit and are managing the routers at my location, but I need to know how to allow machines on my internal network to access resources across this new dedicated point-to-point circuit.

My existing network is setup as follows -

There are two T1's coming into two separate routers:
- From router A, an ethernet cables plugs into the back of a loadbalalancer device.
- From router B, an ethernet cable plugs directly into a switch on VLAN1.
- The loadbalancer has an ethernet cable plugging into VLAN1 as well.
- The PIX firewall is also plugged into VLAN1. The PIX uses the loadbalancer as the default gateway to access the internet.
- All internal machines reside behind the firewall and are using the firewall's internal IP as their gateway.

I currently have several site-to-site connection on my firewall, therefore its imperative that my internal machines continue to use this as their gateway. Also, I would like to put a firewall behind the routers for this dedicated circuit to protect my internal resources from their network.

Hope this gives some insight. Please let me know what options I should explore.

i would think the easiest way would be to have a static route on your gateway router point across the T1 for the address range that your partner uses.. this way your gateway will decide to route traffic destined to your partner via the T1 instead of the internet...
can you plug the T1 router into your gateway router somehow?

The gateway for all my internal PC's is the inside addres of my PIX. Would I be able to add a static route on the PIX so that traffic intended for this business partner is routed over the dedicated circuit? If so, how do I go about configuring my network so that my PIX can communicate with the new router for this dedicated circuit?
