After upgrading old C2500 analog dial-in router with ext. modem pool and with IOS v.11.2.17 to new C3845 router with int. NM-8AM-V2 and IOS v. 12.4.10 i have folloing problems:

1. ppp session does not starts automatically with

'autoselect ppp' command in configuration

2. ppp session starts only when both 'autoselect ppp' and 'autoselect during-login' are configured, but remote users need access both EXEC-mode and PPP-mode w/o 'autoselect during-login' command and Username prompt.

Any ideas?

Removing "autoselect during-login" and adding "autoselect timeout 5". Doing this will allow AAA authentication not to be taken immediately after the connection is made.
