Newbie routing question on 1841

Hi all,


I believe I am having a routing issue on a 1841 router.


The connection is like this (IPs changed):


ISP router (10.87.94.77/30)

|

|

1841 Serial (10.87.94.78/30)

|

1841 FE0/0 (192.168.100.1)


I can ping and trace to the internet from the serial interface but not the FE0/0 interface (or the FE0/1 which was setup just to see if there was an issue with the other interface).


I am using a static route:


ip route 0.0.0.0 0.0.0.0 Serial0/0/0


It just isn't working.


Any ideas on what I am missing? I expect it is something basic, but I am not sure what.


Another thing is that when doing a show ip route, I get:


Gateway of last resort is 0.0.0.0 to network 0.0.0.0


Any help would be greatly appreciated.


Thanks,


Matt

Hi,


you are missing NAT.

I suggest you quit with the SDM now and do manual configuration that will permit you to learn how things work:


interface serial

ip nat outside


interface ethernet

ip nat inside


ip nat inside source list 101 interface serial overload


access-list 101 permit ip 192.168.x.0 0.0.0.255


replace x with whatever network you will be using.


hope this helps, please rate post if it does!
