I'm struggling to set up a Netopia R3100-S ISDN router to use a BTconnect
dial-up account, and looking for help.
* I can connect to the BTconnect account OK - same access number, username
and password - using ordinary modem.
* I can connect to a Demon dial-up account OK on the ISDN router, using
configuration identical except for the access number, username, and
* BT support confirm that the access number should work with ISDN.
When I attempt to connect, the router's log shows the following:
PPP: PAP authentication failed, Channel 1
Reason: Remote refused our authentication attempt
I also trying changing the authentification method from PAP to CHAP: this
produced an excitingly different result, in that it appeared to authenticate
but instantly disconnect. From the log:
PPP: NCP up, session 1, Channel 1
Final (fallback) negotiated auth: Local NONE, Remote CHAP
PPP: CHAP remote accepted us, Channel 1
Remote name: <six letters>
PPP: MP negotiated, session 1
Remote EDO: 06 01 <12 hex digits> 0
Requested Disc. from DN: <btconnect number>
Received Clear Confirm for our DN: (not supplied)
The switch from PAP to CHAP was suggested by the BT support person we spoke
to - however they had nothing to suggest about the instant disconnection,
nor indeed about the signifigance of CHAP apparently authenticating when PAP
didn't - indeed, they also couldn't explain the difference between PAP and
Any suggestions, or just light cast, would be gratefully received.
