The IP/MAC must be fixed .
Another way that i apply is simply to set a liust of user with password on
the router/gateway to assign a SNATTED address to each user.
Unauthenticated user would just stay inside, as soon you are
authenticaded you get a real address and so you can go äway"of
course you can select if you eant a plan or a firewalled connection.
This way one user that got a new computer or just change his NIC has
no to reregister, but just log via software.

the approach is OS independent.
