Did this get mangled in transit? You're missing the '216.113.2.4' entry. I don't see your MAC address anywhere either. > 3) $ ping 127.0.0.1 > PING 127.0.0.1 (127.0.0.1): 56 data bytes > 64 bytes from 127.0.0.1: icmp_seq=0 ttl=255 time=0.120 ms > 64 bytes from 127.0.0.1: icmp_seq=1 ttl=255 time=0.083 ms > 64 bytes from 127.0.0.1: icmp_seq=2 ttl=255 time=0.081 ms > ^C > --- 127.0.0.1 ping statistics --- > 3 packets transmitted, 3 packets received, 0% packet loss > round-trip min/avg/max/stddev = 0.081/0.095/0.120/0.018 ms Whoo-hoo!

Looks like you send out packets, they go to the gateway which (as it should) does not do anything with them. You machine does not seem to know that it is 216.113.2.4 and sends the packets away rather than to itself. -- Crist J.
