ADSL Configuration on 2811

Hi All,

I have just configure an ADSL interface on a router to dynamically connect to BT network for internet connection.

Below is my running config:

!

interface ATM0/1/0

no ip address

no atm ilmi-keepalive

dsl operating-mode auto

pvc 0/38

dialer pool-member 1

protocol ppp dialer

!

!

!

interface Dialer1

description ADSL Interface

ip address DHCP

ip nat outside

ip virtual-reassembly

encapsulation ppp

dialer pool 1

ppp chap hostname xxxxxxxxxxxxxxx

ppp chap password xxxxxxxxxxx

ppp pap sent-username xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Question:

1. Please How do I configure my Dialer1 interface to automatically request a DNS from the BT network?

2. Which do I need to configure on my Dialer1 interface, is it "ip address DHCP" or "ip address negociated"

3. Do I need to configure an "ip nat pool"?

Cheers!

Hello Lawrence,

2) you need ip address negotiated: it comes from PPP IPCP negotiation not from DHCP

3) you can overload on dialer interface

ip nat inside source list 1 interface dialer1 overload

1) you should be able to use the provider DNs

Hope to help

Giuseppe
