A good smart switch will help with users changing their Mac address also, enabling sticky mac's on a Cisco switch with a limit of 1... first mac the switch learns, is the only mac the switch will let use that port. Course moving users, or anything requires the network admins help, but hey, that just means job security... -Mike -----Original Message----- From: Chris Buechler [mailto:[email protected]] Sent: Thursday, September 30, 2010 9:39 PM Cc: [email protected] Subject: Re: [m0n0wall] Firewall Rules by MAC Address.

But going on the theme of the rest of this thread, you could say "but then he/she can just get someone else's credentials!" That's why you take the approach of not trying to come up with a bulletproof technical solution to a people problem, which is impossible - there are always going to be ways to get around something. If you assign a DHCP reservation, let them know they are not authorized for web access, and the person goes to the extent of changing their IP and/or MAC to get around restrictions you have in place, that's generally grounds for termination. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
