[EMAIL PROTECTED] ~ $ ping -b 202.0.37.255 PING 202.0.37.255 (202.0.37.255) 56(84) bytes of data. --- 202.0.37.255 ping statistics --- 5 packets transmitted, 0 received, 100% packet loss, time 3998ms Looks as if, correctly imho, the gateway machine has had the ping response disabled. This is the reason the machine with the address 172.20.18.55 is using the BOOTP port to do it's discovery work. > On Tue, 28 Feb 2006 08:48, Chris wrote: > > OK, correct me if i'm wrong here, but i take this to mean that owing > > to the shared nature of the cable network, it would be possible to > > have a direct non chargeable path to my friend up the road if he/she > > is also on the same subnet?
