This seems like normal behavior to me. If by "cut myself to the internet", you mean physical disconnection (or all ports blocked), then how would ping receive a reply from google.com? You may be able to make DNS lookup requests, with dig or nslookup, but ping requires an actual connection to the address being queried, which it seems to be disconnected for you (dialup?). Lance Lucas
