I know you probably have your reasons for wanting to do this, but I'm at
a loss as to why you percieve it as an issue..

A user is connected to your PM2-30, the fastest they're connecting is
33.6Kb/s.  What does it matter if they have 1 computer or 10 behind that
connection?  They can't exceed the 33.6 limit imposed by the connection.

If you are worried about these users staying online too long, then
impose time limits, not usage limits.  Honestly, you'll just drive
yourself insane if you try to track down and enforce the "single
computer" rule.

** LAN detection?
**
** Our ISP has a service that is specified as being a "single
** computer".  In
** other words, you should not be using NAT or distrabuting it
** over a LAN with
** things like winroute and D-Link 602's or WebRamps (or even
** FreeBDS and
** userland PPP!).  Being a tiny ISP it is important to control
** bandwidth use
** and abuse.
**
** Customers dial into a PortMaster 2E-30, straight through a
** Dummynet, forced
** to a Squid Proxy (No direct port 80) and then through an
** IPFilter Firewall.
** The Dummynet, Squid, and IpFilter are all on different boxes
** connected to
** our LAN Hub.
**
** I am just looking for a way to trap one or two people who are sucking
** bandwidth across a LAN without paying their fair share of
** the costs.  Any
** Ideas?  Is it possible to see the MAC address of the orignal
** LAN card?
**
** Thank You,
**
** Love
**
