Cisco 827 ADSL Configuration Help

Hi everyone,

I've managed to get my hands on a Cisco 827 ADSL router, which I'm just
playing around with.

At the moment I have not connected the router to the internet, because I
have a cable connection, BUT on Saturday, I'll be taking my router to a
friends house, and need to connect the router to an AOL ADSL
connection....(REALLY, I've tried to convince him to change ISPs).

Anyway, I have found this website http://www.kitz.co.uk/adsl/AOLsetup.htm
which has instructions on how to connect a "normal" router to AOL, but I
don't have any "normal" ones at the moment, and I'd rather use the Cisco
as I'd learn how to use it that way too smile

.

As far as I know, it should work fine, since AOL uses PPPoA.

So I was wondering if anyone has a working configuration for AOL, or
any hints/tips which I could use to get the Cisco router to connect to AOL?

from Googling around a bit, I've found out a few commands and made a
configuration for the router, but am currently unable to test it (since I
do not have an AOL connection). I have pasted it below, could someone
please tell me if its OK, or I've made a mistake somewhere?

Any help truly appreciated.

Hamzah

I don't have AOl so I can't say anything about that, but I would get
rid of the access-lists and firewall and concentrate on the basic
connectivity first.

under ATM0 add:
dsl enable-training-log (so that you can see the training with show
dsl int atm0)
