Cannot route to internet

[DonB]

I am having problems routing thru my lab to the internet.

Please refer to the jpeg.

From the pc on the 192.168.20.0 subnet, I can ping the 1602 routers 192.168.1.201 interface but not the linksys router(192.168.1.1). From the 1602 router I can ping the linksys router. If I put a pc on the netgear router in the 192.168.1.0 subnet I can ping it from the pc on the 192.160.20.0 subnet.

From what I can tell using debug ip packet detail, the 1721 router is sending the packet out the serial port to the 1602 router but is not getting any packets in return.

On the 1602 I am not getting any debug packets for the ping to the 192.168.1.1 linksys router. If I ping directly from the 1602 router I CAN ping the 192.168.1.1 linksys router.

Any ideas? I will post the configs is a min.

Any help would be great

Hello,
where is the config of the Linksys router? How did you setup EIGRP on this router?

Do a "show ip route" on every router, please. Find a way to check the routing on the Linksys router. Don't forget that this router is consumer equipment so its knowledge about routing protocols is limited.
Bye, Tore

Crissa's right. You need to post the config for the Linksys. The other things I would do:

1. Get rid of the "redistribute static" on the 1602.
2. "ip route 0.0.0.0 0.0.0.0 192.168.10.1" on the 1721.

The linksys probably only supports RIP, if that. But there should be a way to enter static routes into it. You probably just need a static route for each of the networks that aren't directly connected.

You guys were right. the problem was with the linksys.

gabrelshorn, you are correct. The linksys only supports rip and on top of that it will not support rip and nat at the same time. Since i am using the nat to the internet I cannot enable any dynamic routing on the linksys only static routes.

I have the redistribute static in there just to see how it worked. This was not the issue. The problem was the linksys did not have a route back to the 20 subnet.
