default route not working

Unanswered Question
Jul 4th, 2008

I have a 2811 router with a DSL connection to my ISP. On the router I can ping out to the ISP DNS server across the Dialer1 interface. But on from my Lan traffic stops at the 2811.

I do have a static route of ip route dailer1

Also when i do the show ip route it does show the default route going out the dialer1 interface.

Any suggestions?

I have this problem too.

Yes you need to add the route.

ip route dailer1

it would be better if the configs could be posted.

You need the nat configuration

int dialer1

ip nat outside

int fa0/0

ip nat inside

ip nat inside source list 1 interface diler1 overload

access-list 1 permit x.x.x.x

replace x.x.x.x with you private IP addresses.

Please rate post if it helps!

Hi Paolo,

I was wondering how you can answer that without any configs.

Great Hats Off.............

I do not want to put words into the mouth of Paolo, but on the basis of experience (without seeing any config) if the symptom is that the router can ping outside but devices on the LAN can not ping outside the most common source of the problem is that NAT is not properly configured.
