Modem trouble

Hello group,

My problem is a simple one, but I can't really find a straight answer on the Cisco site, maybe you guys can point me in the right direction.

All I need to do is make our Cisco 2501 router dial an ISP when a certain user launches their IE browser.

The modem is connected to the aux port with a rollover cable. The modem is a MultiTech, Multi Modem II.

I'm having quite a lot of trouble understanding how to configure this on our router...please help!

Re: Modem trouble

You need to have all the PC's with a default gateway as the ip address of the 2500. After that here is the sample config for router dialing out on the aux port running ppp with isp..

Here the sample config is for 2600..The config will be the same for 2500 too..just aux port line number will be different.

Re: Modem trouble

you need to configure a dialer-list specifying IP as interesting

you need to bind the dialer-list to the async (aux) port

use PPP as the encap

you should enable ip domain-lookup

you need to have the PAP or CHAP parameters setup with you ISP
