From my dhcp/gateway machine... Windows clients have arp tables like this arp -n|grep 192.168.1.146 192.168.1.146 ether 50:e5:49:3d:88:a3 C eth0 192.168.1.146 ether 50:e5:49:3d:88:a3 C eth3 Linux machines have arp table like this. arp -n|grep 192.168.1.158 192.168.1.158 ether 78:e7:d1:c8:dd:3f C eth0 The network diagram is roughly like this. Intranet > 8 port linksys switch, uplink port connects to Hp Procurve switch vlan 100 intranet. the linksys switch also connects to the dhcp/gateway on eth0 The gateway connects on eth3 to the hp procurve switch in default vlan 1 the hp procurve then connects to my internet router from vlan 1
