Hope someone can help me! I'm sure it's just something simple I've missed.

Settings are for UK ADSL PVC 0/38 etc.

Thanks!

your virtual access is not coming up.. so you wont get your ip.. are you sure your username and login are correct?

i think your dialer is missing


conf t
int d0
ip mtu 1492
ip tcp adjust-mss 1452
dialer idle-timeout 0
ppp authentication chap callin
 
ppp authentication chap callin

I would actually configure both PAP and CHAP, but you definitely need to tell it how to authenticate the ppp session.
Also...under the dialer interface...
ppp ipcp dns request
ppp ipcp wins request.

Thanks Guys!

I was typing the wrong password in, it's been years since I changed the setup.

Thanks very much!

The thing to do to troubleshoot is
debug ppp authentication
debug ppp negotiation

Burt
 

Cheers Burt,

I actually did debug ppp and saw Auth timeout however I was so certain I had the correct password... cheers for your help.
