Re: Basic router config

Hi,

Take a look the Cisco DSL Router configuration guide at the following URL.

Re: Basic router config

Penbee,

I am not sure what exactly your problem is.

As you are able to ping the ISP DNS address that indicates you have Internet connectivity. Are you having problems with DNS? Can you configure the 'dns-server (ip-address)' with the correct IP address assigned by your ISP as that's not set correct in your configuration.

It that's not the problem pls. explain what problem you are having.

HTH,

File attached pls

Re: Basic router config

No problem.

Can you try adding the command 'ppp authentication chap' to the interface dialer 1.

HTH,

Sundar

Re: Basic router config

Never mind.

I see a problem in your config. Your access list is misconfigured. Can you put this config in.

no access-list 1

access-list 1 permit 192.168.0.0 0.0.0.255

Re: Basic router config

Hi Sundar,

Have corrected the access-list but still same old prob.

I can ping my ISP DNS servers and also the PPPoE sessions have negotiated successfully.

What I am not sure is if I have to set the gateway IP address address on an interface or not?

Pls check the configs again

Penbee
