Hello! I am wondering if anybody can help me in finding ways to block connection to the server using MAC address. The scenerio is
I have a DHCP server which also acts as a network gateway for my entire LAN. I used to use IP for blocking certain computers to browse the Internet (I have squid running in the same box), but then they would change their IP and get into the Net. I am using RH8.
Now, can anybody please tell me if I can block these connections using MAC address through IPTables, and if yes, how?
If no, what can be an alternative means?
The fact that these connections are using other IP is both annoying and occassionally problematic for me since they are colliding with the eligible IPs as well.
Distribution: Slackware 10, Fedora Core 3, Mac OS X
Look at the various modules that can be used for iptables. Look in the kernel configuration screen under networking options->ip netfilter configuration->MAC match address support. THat should do the trick.
Actually setting it up is a bit beyond my experience but the documentation should help you.
