Hi! I was trying to add a permanent arp entry to my interface eth1 as shown below: arp -H ether -s 172.16.5.125 xx:xx:xx:xx:xx:xx pub When I try to ping this host from a Windoze client following happens: ARPREQUEST 2 times but there is no reply arp -n brings up 172.16.5.125 * * MP eth1 How do I get my machine to reply arp requests? Thanks markus
