Remote Access Via Mac Address and Unknown IPs
Hello,
I have seached Google and the archives but I can not find anything that tells me how to use iptables and mac addresses to allow a user at a remote location to access a server when the remote IP address is unknown.
What I am trying to do is setup a rule where a client with a laptop can roam and still have access to certain ports (primarily 427 amd 548 for atalk access). I want to restrict access by mac address, but I can not figure out how to do it given that I will never know an IP address where the client might be coming from.
Is there a way to do this with iptables?
I figure I have to have some kind of established tcp communication before I can identify the mac address, but it is like I have to open the ports up to the world and then drop sessions not coming from a particular mac address.
Can someone help me with this one please?
Thanks,
Murrah Boswell

You can't. A host MAC address is only visible on local network. After the first router, you don't see it anymore...
