Adsl config

[partha_b]

I have a Cisco 1721 router with two wic Ethernet card and one fastethernet.

I have two internet isp one lease line and another adsl line. The adsl modem is non cisco product.

Please Help me

I need both to be connected in my router so, if any of them is down then internet could not stoped. pl help me to configure the following network.

To begin with, configure two "ip nat inside source list xx interface etethernet X overload" statements for the two int, and two default routes.

Verify that you can work the internet and both circuits are used at the same time.

After that a more advanced configuration can be done based on specific requirements.

The best would be if you can get a WIC-1ADSL card to connect directly to ADSL and eliminate the existing modem.
