BT Office ADSL config for 1760

[Frenchie2069]

Does anyone know how to get a 1760 working with ADSL for BT? I have the following at the moment:

interface ATM0/0
no ip address
no atm ilmi-keepalive
pvc 8/35
encapsulation aal5mux ppp dialer
dialer pool-member 1
!
dsl operating-mode auto
!
interface Dialer0
ip address x.x.x.x 255.255.255.248
ip access-group 100 in
ip access-group 110 out
ip nat outside
ip inspect Management in
ip inspect Internet out
encapsulation ppp
dialer pool 1
dialer-group 1
ppp authentication chap callin
ppp chap hostname xxxxxx
ppp chap password 7 xxxxxx
!

However it wont connect. I have enabled dialer debugging and get the following when I try to ping outside:

Jun 26 18:18:32: Di0 DDR: ip (s=x.x.x.x, d=207.46.134.155), 100 bytes, outgoing interesting (ip PERMIT)
Jun 26 18:18:32: Di0: No free dialer - starting fast idle timer.

show d0 shows this:

Dialer0 is up (spoofing), line protocol is up (spoofing)
Hardware is Unknown
Internet address is x.x.x.x/29
MTU 1500 bytes, BW 56 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation PPP, loopback not set
DTR is pulsed for 1 seconds on reset
Last input never, output never, output hang never
Last clearing of "show interface" counters 04:29:08
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: weighted fair
Output queue: 0/1000/64/0 (size/max total/threshold/drops)
Conversations 0/0/16 (active/max active/max total)
Reserved Conversations 0/0 (allocated/max allocated)
Available Bandwidth 42 kilobits/sec
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
0 packets input, 0 bytes
0 packets output, 0 bytes

I thought that it should be bound to a Virtual-Access interface, but it is not happy...

Is the PVC 8/35 correct?

Anyone have a clue?

TIA,
Michael.

Are you sure that they are using chap for authentication, just include the following in your config incase that are using pap:

ppp pap sent-username xxxxx password xxxx

And take out your:

ppp authentication chap callin

statement.

Also include the following under global mode:

ip cef
vpdn enable
!
vpdn-group pppoe
request-dialin
protocol pppoe


And

ip nat inside source list 1 interface Dialer1 overload

Try that - I can send you a full config if you want, but it is for our Telco here in South Africa, so might be a bit differnt?

Hi Ian

I have just been configuring my couter for ADSL (cisco 827)
i was wondering if you could tel me if the config looks ok?

and if so great if not where did I go wrong.
then the next step is the IPsec stuff no problem there done that a few times.

Any help would be great
Thank
Lyndon
