If direct, are you certain that you are cabled correctly? I would think you'd want a crossover cable instead of a regular cable. What are the results of the following commands on the Linux host: route -n ifconfig eth0 service iptables status ping -c 4 192.168.1.2 arp -a And what are the results of these commands on the XP box: route print ipconfig ping -n 4 192.168.1.1 arp -a Thanks, Thomas
