How do I grant access to a server based on mac address? (This is a VPS)
According to google searches, this is the syntax to allow a certain mac address...
iptables -A INPUT -m mac --mac-source c4:2c:03:30:14:1f -j ACCEPT
I get useless error messages along the lines of "iptables: Unknown error 18446744073709551615". (Tried it on ubuntu and centos) Is my syntax wrong? Or is the concept fundamentally flawed. Like, is it impossible to filter mac addresses on a VPS. What am I missing here?
