Hi all I just added this to my FW $IPT -t nat -A PREROUTING -i eth0 -p tcp -s 1.2.3.4 -m mac --mac-source 00:00:21:41:59:e6:00:13:80:9d:38:82:08:00 --dport 3389 -j DNAT --to 192.168.111.124:3389 $IPT -t filter -A FORWARD -i eth0 -p tcp -s 1.2.3.4 -m mac --mac-source 00:00:21:41:59:e6:00:13:80:9d:38:82:08:00 --dport 3389 -d 192.168.111.124 -j ACCEP And I keep getting this message iptables v1.3.3: Bad mac address `00:00:21:41:59:e6:00:13:80:9d:38:82:08:00' I did a check on the message logs, and I see this in the line for MAC address, the and line matches [INPUT ]: IN=eth0 OUT= MAC=00:00:21:41:59:e6:00:13:80:9d:38:82:08:00 If someone would be so kind as to help me understand this, I would be most grateful. Is it possible to get the mac address for a mac on the internet, line above I thought I could use this. Kind Regards Brent Clark
