Hello netfilter list, I have a fairly good knowledge of iptables etc...but there is one point I would like some clarification on. This is from the iptables tutorial located here: http://iptables-tutorial.frozentux.net "6.4.3.2. MAC match The MAC (Ethernet Media Access Control) match can be used to match packets based on their MAC source address. As of writing this documentation, this match is a little bit limited, however, in the future this may be more evolved and may be more useful. This match can be used to match packets on the source MAC address only as previously said" Are MAC addresses unique for all ethernet cards? What I would like to know is could I use this rule to allow ssh connections ONLY from my notebook no matter what its current IP address happens to be, and drop all other connection requests?
