I'm brand new to Cisco routers so I apologize for this stupid newbie question. I've installed a dozen consumer routers (buffalo, Linksys wrt54g, etc.) but never a Cisco. This is a model 851. I'm trying to configure it with Road Runner using the GUI interface. I know I don't have the ability (or desire) to program it via the console. I have the SDM software installed and I can change configurations but I am unable to ping any domain name or external IP address.
This is the only router on the network. Internet works fine with no router or with a linksys.
I'm a bit overwhelmed by all my options. Right now I'm just trying to get simple web browsing access. Eventually I hope to configure it for a VPN access so a user can call into the network via his laptop. That'll be a different question if I ever get that far.
Any suggestions on what I need to do?
