Cisco 837 Routing issue?

I have a 837 that I'm getting setup for a charitable cause. I copied most of another operation setup but am having issues with the routing, I think.

THe ATM appears to be correct using the "ping atm interface 0 0 35 end-loopback" command.

I have pasted the run-config below:

   

version 12.3

service tcp-keepalives-out

Re: Cisco 837 Routing issue?

It looks like you're missing the "ip nat outside" command on the dialer interface.

Try this:

access-list 10 permit 10.0.0.0 0.255.255.255

ip nat inside source list 10 interface dial0 overload

int d0

ip nat outside

And you may need to change your default route to point to dialer0 instead of atm0...

There's some other documentation that I'm finding from Cisco that states to put the nat statement on the ATM interface though:

http://www.cisco.com/en/US/docs/routers/access/500/520/software/configuration/guide/520scg_ppp_atm_nat.html

HTH,

Cisco 837 Routing issue?

Hi,

Routing is also disabled so you should enable it with the global config command: ip routing.

Regards.
