Hello, I have a cisco 871w router that I'm trying to incorporate into an existing network. I have FastEthernet4 (WAN port) plugged into an ISP device, which I don't have access to. I have the address set to use dhcp, which is successfully recognized and I see that the interface gets a valid ip address that I can ping with other computers on the same network.
Problems:
I am logged into the router via the serial port and I cannot ping websites on the internet. I am able to ping sites that are hosted inside the WAN, but when I try "google.com" for instance, I see it sending out packets, but none are received. It resolves the hostname from the local DNS server, but there are no packets received.
Configuration:
I'm really new at this, so I was wondering if you guys could take a look at the commands that I type into the console to set up the router. I'm missing a lot of stuff. This is what I've been able to piece together using google and the software manuals:
enable

Thank you very much for your help!
