Cisco 806 to LYNKSYS router connection

[SF18C]

Forgive this probably obviously simple question but how do I get my router to find my network. I have my network connected together with a linksys router, (I'm using it because it has 100MB connections). But my ISP connection comes into a Cisco 806 router using PPOE, I connected the WAN side of the Lynksys to the E0 interface on the Cisco. I can access the internet fine, but I can not ping any PC's on my network from the Cisco device, I'm tring to set up a Syslog server but the Cisco can't find the server. Any ideas?

Probably because the LinkSys is running NAT.


Try plugging the e0 to the INTERNAL side of the LynkSys, thereby only using the Switch. Of course, if you don't have DHCP set on the Cisco, you'd need to assign the 10.xx.xx.xx addresses to the computers. You'd also have to change the default route on the LynkSys

You are doing NAT on the Cisco, and not on the Linksys, right? It looks like you are double NATing the traffic, once in the Cisco and once in the Linksys. But maybe, since RIP is on, you are learning the 192.168.1.0 network via RIP. Otherwise, the router won't know about the network.

My suggestion:
Turn off NAT in the Linksys, if possible.
Add the following route to the 800:
ip route 192.168.1.0 255.255.255.0 10.10.10.2

But the above solution will work, too, but you have to add the route. Otherwise, the 800 won't know where the network is, and will forward the traffic to the Dialer interface.
