I have a single DSL connection I share with 7
computers and wish to divide the bandwidth. I will be adding another one
later and hope to divide the traffic and re-route to one if the other fails, but
that is a nother project. The connection is 384/128. I am able to
control the downstream traffic, but the upstream traffic has proven to be more
challenging. It seems that the Masquerading takes place between adapters,
so all the traffic to the outbound adapter appears to be from the same IP.
I can control the traffic if I specify the IP of the outbound adapter, but
reference to the LAN address has no affect. Here is a summary of my
setup
eth1 (internet)
|
eth0 (LAN)
|
Switch
|
Comp1-Comp2-Comp3-etc.
I tried to filter the outbound traffic on eth0 by
adding subclasses for outbound traffic to eth1 and filtering by src but I
could not seem to get that to work either.
Here is my latest effort:

I would also be very interested in documentation
that clearly defines the commands and variables. For example. what is prio
and what is the significance of it's value as with weight and
maxburst. Can I filter on src
and dst on the same line?
Thanks,
Kurt
