Configuring ADSL card on Cisco 2691 Router

[skk391]

Hi all,

I have a 2691 router that I use for internal routing. I have installed an ADSL card into a spare slot. I need some guidelines on how to configure it so that I can provide internet connection to one of the subnets.

I have done a little reading... But wanted to put it pass this forum...

I need to configure the ATM interface I take it that this is the card interface itself.

Then map this to the dialler 1 interface ? unsure what this is. Is it here where I enter in the internet connection details

Then configure NAT ?

Thanks

Just a little update..

I have got the following details from my ISP:
encap type
vpi
vci
static ip
auth

I take it that I need to confirm the ATM card with these details but I am unsure what the dialler int is and how to config it?

I am uk based and we set our DSL's like this.

interface ATM0 (SLOT NUMBER)
no ip address
no atm ilmi-keepalive
pvc 0/38
encapsulation aal5mux ppp dialer
dialer pool-member 1

interface Dialer1
description *** ADSL ON BT NUMBER XXXX XXXX ***
ip address negotiated (May be different for your ISP)
ip nat outside (If required)
ip virtual-reassembly
encapsulation ppp
dialer pool 1
dialer-group 1
ppp chap hostname "username"
ppp chap password "password

Thanks TheProvider...

any chance that you will be able to give me some background on this config... trying to work out what is going to so that I understand it better. Is the ATM the actual ADSL card in the router and what is the dialer interface. What is its role?

I take it that the 'dialer pool-memener 1 'maps' the ATM interface to the dialer interface ?

Many thanks

The ATM is indeed the actual card. The Dialer interface is as such virtual.

The Dial pool member is just using what is stated in the dialer as Dialer pool,

 

[TheProvider]

you would also need an ip route

0.0.0.0 0.0.0.0 dialer 1 and a specific NAT statement if you are natting.

Thanks,

The setup is at work so I get it configured hopefully tomorrow. May have some questions for you then!

thanks again ...
