My home network consists of a 3com office connect and 2 PC connecting to it through wireless. In the 3com config, i can see the Internet IP address is 184.108.40.206 but i am not able to ping it from my office network. The router actually connects to the socket provided by my building, so i havent really subscribed to any ISP. I don't know if this IP is real and can be accessible from outside. Or the issue is that the router just doens't repsond to my ping. Any suggestions? Thanks!
