801 - Incoming connections

[AMS100]

I'm new to this Router malarkey, so any help is appreciated. So far I am able to set Cisco 801 routers to dial out on ISDN and connect to a remote IP address. The problem I'm having is trying the opposite - Dialling into a 801. It doesn't seem to be as straight forward, could anybody point me in the right direction. Thanks

Hi

below is a basic setup (ISP dialout and remote user dialin):
Certain settings are country specific, eg. we use Switch type Basic Net3 and no SPID's that might be different in your case. Since this was only a test installation I didn't care much about security, eg. no dialback etc.

(helpful troubleshooting commands:
- debug dialer
- debug ppp authentication
- debug isdn events
If you're connected through a Telnet Session, enter TERM MON to get the debug outputs displayed.)

Hope this helps!

regards,
Alan
