PPP connection over ADSL with CISCO 836

[csakosadmin]

Hi all,

I am kind of new here so I appologize in advance for any stupidity that I might say here. I am having problem with CISCO 836 configuration-I cannot get PPP connection to my ISP.

We got sort of fixed IP address from our ISP, I got PVC numbers, user name and pwd in order to access ISP.

With configuration bellow I can see in CRWS the follwoing:

LAN coonection up, WAN connection UP, also the right IP addresses, router also detects connection type and speed however I cannot ping from router or my ISP.

Hi,

thank you for your resposne. I did all the things you have written however I am still not connected to my ISP. So, what I did was I test my router with its internal test function. In resposne I get the following results:

Connection to your ISP: Failed

Testing PVC: Failed

and it says please check your PVC number.

Now, the reason I didn't post my reply is that I had to get in contact with my ISP person who chekced that PVC number for me. He checked and said I got the right PVC number so now I am kind of confused. Is my PVC ok or not, since testing function of my router says please check your PVC number ... does anyone know why?

Secondly, my ISP said it can detect my router (adsl modem) online .... so I don't really know where in my configuration I am still missing the part in order to get connected to my ISP.

Bellow is my currnet configuration.

Pleassss help!!!!

In your current config I'm missing the pvc statements which were in your previous config.

[csakosadmin]

Well, I might erased that line ... however I got my PVC in. Well, I am still stucked at this PVC problem ... I contact ISP and they gave me another PVC number .. default ... 0/32 ... however I am still having the same problem ... so if anyone has any new suggestion or have experience with cisco 836 please let me know.

I am taking my cisco 836 to my ISP today.

[csakosadmin]

I got PVC No. Ok now, and I can connect to my ISP now ONLY with router (router can ping ISP), however I cannot get any connection with my PC. It seems to me that I'm doing something wrong with IP DOMAIN configuration.

Also is this line mendatory for authentication in my configuration

****ppp pap sent-username password 0 ****

This is my latest configuration.

Just to let you know. Everything with configuration considering Internet connection was Ok, however PVC number was all the time wrong. In my case for my ISP the right PVC number is 1/32.

Thanks all for help!
