No internet after changing username/password for adsl on cisco 2811

[mipl45023]

     Greetings,

I have a 2811 cisco router which is connected to a ADSL modem via fa0/1. When i changed the username and password for ADSl udner the dialer interface, i loose the internet connection. the new internet account is fine since i can login to internet directly through the wifi available on the adsl modem.if i put the old username and password back it works. Not sure how to sort this out or figure out where things are going wrong. putting the config below. suggestion is highly appreciated.

The router is on the perimeter , where the leased line , adsl and the PRi line terminate. from the router, the connection comes into a ASA5505 firewall and from there into the internal switch.

havent put the whole config since the router also has CUE runnign on it.

[mipl45023]

the default route is set to leased line so that the smtp traffic only goes through that  and for internet traffic coming from the itnernal lan, it is routed through the adsl line

Hello raj ,

Hi Raj,

It is expected that when you change the username and password on the dialer , it will not be up until you put back the correct username and password.

please correct me if your query was something different.

Thanks

[mipl45023]

Neil,

did ppp debug and not getting any output. if i am change the username and password, the dialer interface looses the ip. the only thing that works is pinging public dns like google etc, whic i suppose is goign through the leased line interface.

anything else to try. need to get rid of this. should i post the whole config. its a PBR that is happening on the router. for smtp ,the leased line is used and for http, the adsl. the wireless modem that is hooked up to the fast ethernet interface on the router works without hassle. i can hook up to that directly and browse itnernet without any issues. but through the lan, it is not working

[mipl45023]

sh interface dialer shows, line protocol is up ( spoofing). there are no other errors or debug information showing up on the router, unless i am not looking at th eright place.

Hello Raj,

This is what intrigues me in your debug output:

Jul 13 08:14:27: Vi2 LCP: I TERMREQ [Open] id 248 len 4

The debugs clearly show that you are authenticating correctly to the other party and that the IP protocol is brought up fine. Immediately, however, the PPP session is torn down by your ISP by the termination request as highlighted above - after the link has actually been brought up totally successfully. The reason is not indicated.

I believe you should discuss this with your ISP - he may have better insight into why its access device is closing the PPP session to you. Show him this debug and point out that the TERMREQ message is coming from his devices after the PPP+IP have been succesfully negotiated and link should have actually started working.

Best regards,

Peter

Hi Raj,

These two lines indicate where the problem is, but everything seems to be okay, authentictaion LCP etc.  The only thing I can see wrong is these lines and the fact the remote side will not do CDPCP with you (but you can fix that with no cdp run in global config).

Jul 13 08:14:27: Vi2 LCP: I TERMREQ [Open] id 248 len 4

Jul 13 08:14:27: Vi2 PPP DISC: Received LCP TERMREQ from peer

I would asvise speaking with ADSL provider about this, everything seems absolutely fine and there is no reason specified for the termination request from the peer.

Ask them for their PPP config and give them this output and highlight the above.  Seems very weird, on the off chance though try disabling CDP, can't see why that would cause them to send termination request though.

Thanks again for guidng through. The issue has been sorted out and was indeed a trouble with the ISP.
