Three ISP conections,. How to configure?

We have a 2600 router with an internet conection with public IP and NAT to inside/outside access mailserver. We want to add another conection to inside access webserver and a DSL conection to navigate (via proxy).

I don't how to config this policy. Firewall has a default gateway to Cisco 2600, and Webserver and Mailserver have default gateway to Firewall.

Mailserver will use Internet 1, Webserver Internet 2 and LAN will use Internet 3.

Any suggestion??



This is the network :

..................->> Cisco 2600 --> Internet 1

LAN ---> Firewall | --> Internet 2


..........^.......->> ADSL router -> Internet 3
