Dividing a bandwidth

Hi,
I have a network of about 80 computers, most of them are Win98 stations. I need to guarantee a certain subnet (administration staff computers :)) always have a certain garanteed bandwidth to an outer world. The network is connected thru a computer running iptables, and acting as firewall. Thought that iptables should give such a functionality, but couldn't find it.
Just pointing a software to do the job will be enough :)
Regards, L.

The tc (traffic shaping) app included with the iproute2 toolkit should do exactly what you want - you can dedicate bandwidth based on a number of criteria, including source IP address...  I used to use it to guarantee a certain amount of bandwidth for interactive sessions (i.e. ssh, telnet, etc).

Be warned - the 'tc' docs are not that great...

Cheers,
-Jon

.. to complete The--Captain's comment: iproute2 (tc) can be combined with iptables (see MARK flag)

I provide a sample script that should do what you want, if you modify it a bit.
