[Karlnet] limiting bandwidth

[LaRoy McCann <lmccann@roachconveyors.com>]

How do you limit a user to a certain bandwidth?  The only setting I can 
find on the karlnet firmware is Max Tx Rate in Kbits / Sec.  Actually this 
is a speedlan 8000 series box, but it uses the karlnet firmware.

If this sets only the Tx side, then you are only limiting the upload speed 
and  not the download speed.  I want to limit the speed that a user 
downloads data to their computer.

I know the connections are sold based on the speed that a user wants to pay 
for, but just am not sure exactly how to limit that.

If the wireless link will not do that then what is everyone else doing to 
limit a user to a certain bandwidth.

I guess I could setup a linux box and use iptables to limit each user.

Sorry if this issue has been beat to death before.

Thanks
