I am trying to configure the WAN connection on a 2811 series router, but am not having any luck. I'm new to the Cisco world, and I'm trying to set up the router with an existing broadband cable connection. I configure the interface for 'Outside', set the static ip\netmask and create a NAT rule between this outside interface and the routers inside interface. However, when I test the connection on the router, I get an error that reads: "To test connectivity, SDM tries to ping the configured DNS servers. However, there is no configured route to any of the DNS servers through the selected interface." I go into SDM - Additional Tasks - DNS - Enable DNS and then add the DNS servers my ISP provided. Then, I get an error that reads: Ping to the destination host(s) failed. The possible reason may be one of the following, 1. The detected DNS servers or the IP address or hostname specified are unreachable or not responding." Not sure what to do here.
I have this problem too.
