That would probably be preferable in this case to MAC Pass-through, as
with MAC pass-through, if the users are gaming when the timer expires,
the game freezes and they have to open and browse in a web browser
before they can return to the game, in which they have then more often
than not died - this is generally happening after hours, and is not
going down well.  :)  You know gamers...

I'll look into this option.  I agree that the security is less with this
than with MACs, but with the ease of altering one's MAC address (though
this isn't likely to be THAT easy to those users on this LAN) its not
that much less secure.

Excellent.  I know I'm not the only one asking for this functionality -
there have been others.

Agreed.  Maybe if I changed the subject of this thread it would have
confused people less, however I thought that wouldn't be necessary as
people generally prefer the previous information to remain intact than
to have it all deleted by starting a new thread.  Looks like I was
making unfounded assumptions - at least you can see where I'm coming
from.
