Hi Everyone,

Sorry for wasting everyone's time. I found a configuration problem on the calling router itself.

I performed some debugs on the answering router to see where the PPP negotiation was falling over and found that it was trying to do a two way authentication. I modified the router so it was a unidirectional authentication (using the command 'ppp authen pap callin' on the dialer interface) and all was well.

Once again, sorry for wasting everyone's time....

Hi Everyone,

I'm running a Cisco 3640 router as the main dial in NAS and I'm trying to connect a Cisco 801 router into it using ISDN.

I know the configurations of the boxes is correct as I have the setup configured and working with local authentication on the 3640.

I'm trying to change my routers over to RADIUS authentication and when users dial in with a laptop everything works great (Showing that RADIUS is configured correctly for a normal dial up user). Using the Cisco 801 to dial in I get authenticated (the log files show this) however routing doesn't appear to work.

My problem is obviously due to the RADIUS configuration, however I have no idea as to what it could be. The router authenticates fine but it's as if information isn't being passed to the router as part of the PPP configuration.

My USER file has the following entry which allows the router to connect:

morwell-r10     Auth-Type = Local,
                        User-Password = XXX
        Service-Type= Framed-User,
                Framed-Protocol = PPP

where XXX is the unencrypted password.

The thing that doesn't seem to make any sense is even though I know the routers are connected, the 3640 does not show a connected user on any ISDN lines.

Any and all help or suggestions would be appreciated.
