I have an 1801 router and am trying to connect to the internet. I have successful connection tests for the ATM0 and FE0 interfaces, but when I ping external addresses from CLI the best return I get is 40% and I can't connect to the internet / ping from LAN clients. I have set the LAN clients to use the default gateway which is the FE0 IP address, and to use the FE0 IP address as the DNS server.
I have attached the running config and connection results.
Any assistance would be greatly appreciated.
