[LARTC] Ip accounting, masq'ing and bandwidth sharing

[Simon Bland <angel@khaosse.net>]

I'll cut to the chase of what I'm trying to do..

I've set up my system with a 56k dial-up connection on the gateway, and 3 
machines on the LAN. I'm using a set of iptables to handle the firewall 
and Masq'ing, and ipac-ng to do the accounting on a per ip basis for each 
machine on the LAN's usage.

All that's pretty trivial.. What I want to do next is be able to guarentee 
bandwidth to each machine on the LAN, so that 1 person trying to pull 
large amounts of data doesn't totally lock the others off being able to do 
whatever they want to use it for..

From what I've read this can be done by applying a set of queues on the 
eth0 side of the gateway machine, but that doesn't seem to make sense (how 
do the queues there prevent the modem from being choked by the incoming 
data?

What I'd like is either an explanation of how queueing on eth0 works for 
what I'm doing, or a set of rules/explanations of how to set up an 
appropriate set of queues on the ppp interface that handle the masq'ing 
settings..

Hope that makes sense..

Thanks. :)
