I tried searching MARC for this one and couldn't find an answer... I have setup logging on my FORWARD chain with: iptables -A FORWARD -j LOG --log-tcp-options --log-ip-options It's logging just fine and showing up in my logs, but it's missing the MAC address. I've seen the MAC address show up in logs from other peoples' posts and such. Am I missing a log option switch? Possibly something not compiled in my kernel? Not loading a module? Thanks in advance... Khanh Tran Network Operations Sarah Lawrence College
