1701 - Can ping WAN side but no access LAN side

[stompin]

I have a cisco 1701 ADSL router and when I telnet in I can ping and trace across the internet - WAN seems OK. However, if I go LAN side I cannot connect to the internet. I can ping the routers LAN side E0 port from my LAN so have connectivity there but no further. Any suggestions would be nice.

Please post config....sounds like a nat or default route problem....

Is this router supposed to be your default gateway ??
Check if it is configured on the workstations from your lan.

Also check your dns settings on the workstations from your lan...

Joamon - I think the same but cannot find out why cus I don't want a NAT solution. WE have a Firewall which takes care of NAT before it hits thr router and then out onto the ADSL Network. Here's the config though...

OK...no nat needed on 1701 router......do however need default route....

IP route 0.0.0.0 0.0.0.0 XXX.XXX.XXX.XXX

XXX=IP of next hop router. Dialer0 is using static ip so XXX=its next hop.

Sorted the problem - the router called a fixed IP address a dynamic address!! - pls don't ask me why but it worked!

It has a default route in but must have dumped the config when I was messing with the thing.

Thanks for the input.

No problem...glad you got it working....
