I changed the encapsulation on my Windows XP laptop to 802.3 (from Ethernet II, default). I AM able to ping the local router (802.3 framed ICMP in both directions). But, when I try to ping a remote device off of my subnet it times out (sniffer shows packet goes out but nothing comes back). Ping is unhappy. When I ping FROM a remote device to my PC I get inbound Ethernet II packet (ICMP request) and my ICMP reply goes out 802.3. Ping is happy. Why can't my 802.3 ICMP, sourced from my workstation, not make it anywhere off my subnet?
