Point-to-Point T1

[ekinike]

I have an existing network, T1 to cisco router, pix firewall, switches, etc. I was recently informed that we require a point-to-point T1 with a business partner. They are handling the circuit and are managing the routers at my location.

My question is how do I allow my existing network to access resources from this new point-to-point T1?? Please help. This is new to me.

You need to be REALLY specific about what is connected where and how. I am assuming that you have a T1 line which terminates in a Cisco router which then has a PIX directly connected and then your network behind the PIX?

If you are having a point to point T1 put in, which I am assuming is a private "leased line". Therefore, if someone else is managing this my next assumption is that they are providing you with another router for this new Point 2 point T1, which will probably be put directly on your LAN. Your internal machines may have to change their default gateway to this new router and the router will have a default route pointing at your PIX and a route to the remote network pointing down the new T1.

This is all assumption, so you will need to give some more information about teh setup.

Hope this helps.

Hi,

Some more information is needed to answer your question.

Can you post a general network layout and current configs?

The existing network config is 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.

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