Browse All TopicsHi,
I need to connect (dial out ) from a cisco 3640 with a ISDN PRI to Windows (W2k) machines with ISDN modem and RAS.
We try a lot of different configuration but we always were unable to establish a ppp connection
here is an extract of config that use bidirectional CHAP
interface Dialer9
description TEST
ip address 172.16.10.46 255.255.255.0
encapsulation ppp
dialer pool 1
dialer remote-name IT0152
dialer string xxxxxxx
dialer-group 1
no cdp enable
ppp authentication chap
We try also with PAP but again without success
interface Dialer9
description TEST
ip address 172.16.10.46 255.255.255.0
encapsulation ppp
dialer pool 1
dialer string XXXXXXXX
dialer-group 1
no cdp enable
ppp pap sent-username dialin password 7 XXX
This last configuration in particular report an access denied windows error (but user "dialin" is enabled and valid)
We uderstand that callin / callout option help to use a single way authentication (as windows actually does) but sample are quite unclear again.
Up to now we didn't find any sample in cisco that show a template for this configuration, and even Microsoft help does't help
So how we can resolve the problem (a sample config) and /or better understand what is wrong ?

I'd recommend staying with chap.
Now, how is your router getting the usernames and passwords to use for authentication when it dials? The remote-name doesn't do it. What that does is to check if the remote host has that name- if it doesn't, it drops the call. I would remove that line because if the server reports it's name is a bit differently (i.e. IT0152.DOMAIN) the router will drop the call without going further.
We don't see the rest of your config, but barring something else already in place I would add the lines
interface Dialer9
ppp chap hostname xxx
ppp chap password xxx
That will tell the router to send those bits to the server for authentication.
And you also need to add the hostname and password of the server so it can authenticate to the router.
config t
username xxx password xxx
JFrederick29:
i've already activate debug trace for auth and negotiation but callin option is unclear what does it means?.. yes single direction auth but why not "callout" ? (difference etween callin and callout option really unknown). In any case as described I tryed both witout success
mikebernhardt:
we try using pap because of unsuccessfull chap configuration..... I know the difference, but in this moment is more importat to have a solution rather than optimal (or most secure)....
regarding "ppp chap hostname" I will try and let you know but the last step of your comment is quite unclear (you also need to add hsotname and password of the server...). IMHO Windows Host Name doesn't have any password associated .... and I don't think that is possible to specify a passwrd for the windows host... this is the reason for callin/collout command.
Thanks to all
Try configuring ms-chap instead of chap (if the option is available)
Microsoft has implemented a proprietary chap-version (to keep others out of ther net?) .. so perhaps you'll have to connnect with their own protocol or you have to use PAP instead (as this isn't MS-PAP !!)
Possibly the other way works too - if it's possible to tell MS-RAS to use plain chap ... but i don't think so ;-)
Here's a bit of lecture...

if you don't I will post the page publically, it is a page in reference to configuring a 3600 for T1 PRI dialup.
