Dual Internet Connections?

If you want users to use a specific connection, just change there default gateway to the one you want them to use. For the firewall, it depends on what type u are using, but you could buy a low-cost firewall to block incoming traffic.

By using the
ipconfig /setclassid
you could have these computers use a different default gateway. You will also need another NIC in the firewall to connect to the other T1. But the default gateway has to be on the same network you are on and that is probably the address of your firewall or a core router between you and the firewall. So that won't work.

However, if the new T1 is ONLY intended to be used for access to specific IP addresses, you could add a ROUTE command to the firewall for those addresses through that interface. That would direct traffic to those addresses through the proper NIC. The default gateway of the firewall would still point out the old NIC. That would also mean that anyone going to those addresses would use the new NIC. You still need another NIC in the firewall. Hopefully the network address translation rules won't be a problem. How you restrict who uses the applications that would use those addresses is another issue.

If you want to keep your existing firewall then you will have to make sure that your existing firewall can support 2 t's, plus 2 internal IP address (either thru 2 Interfaces, or the same interface - although I wouldn't reccomend the later- ).
Nextyou map the new internal IP address on the firewall to the new T, then you give as the default gateway (or static routes) on the clients that have to use the new connection, the new IP address.

Run the two T1's into a router (Cisco 2600 series comes
to mind) This will go through the firewall. The config on
the firewall and router will determine the use direction.

Good Luck Lee
