I am testing out a Cisco 1841 Router and need to set a route of last resort. I made a static route of "ip route 0.0.0.0 0.0.0.0 172.16.48.1". Then issued the command "ip default-network 172.16.48.1". This now allows me to ping anything on the 172.16.0.0/16 network from the router. But I am not able to ping anything on the internet or outside of this network from the router. Here is my running config and routing table. What am I missing? fa0/0 is facing the network 172.16.0.0/16, and fa0/1 is facing another internal network.
