DialUp To Cisco 3660 Router Fails at Registering Computer On Network

[tereuben]

Hi Guys, I am a new member and hoping to settle in really good. I have a problem. I am dialin into my Cisco Router Serial Interface from a PC running Windows 2000. The negotiation passes Authentication but shortly after, the modems HANGS UP, according to debug log. What do I do? I really need help.

Please see below for config details and Debug LOG.

Current configuration:

Do you have aaa setup on your router. You need to setup aaa and create username and password for authentication. I also use my router as a DHCP server that gives out the IP to the dial-in pc.

Add these lines:

aaa new-model
aaa authentication login default local
aaa authentication login No_AUTHEN none
aaa authentication ppp default local

username test password 0 ras

int async5
dialer in-band
dialer idle-timeout 600
ppp authencation chap
peer default ip address pool dhcp

ip local pool dhcp 1.1.1.10 1.1.1.50

line 161
stopbits 1

I meant interface Serial5/0 not int async5
