Use MAC address filtering with internet sharing
Authored by: _merlin on Oct 10, '04 07:47:48AM

This will not actually stop people from connecting to your network. All it will do is stop the DHCP server from issuing them with an IP address and providing information on router address, DNS server, etc.

Without spoofing the MAC address, a person could still connect by manually entering an IP address, or by using AppleTalk protocols.

It would be quite easy to work out what address range to choose an IP address in, and work out the router address. You'd only need to capture two or three TCP packets before you had enough information to guess with.
