[LARTC] Bandwidth Nazi'ing revisited

[LARTC] Bandwidth Nazi'ing revisited

[George Peverill]

After about a week or more of enjoying a sensible amount of bandwidth on
our
network (after limiting the rate/ceiling of one particular ip on our
network)
I noticed that the rules I had been given weren't infallable, something
was
wrong. For some reason our internal samba traffic (eth1) was also
limited to the rate/ceiling
of my bandwidth throttling script [see below]

It does indeed limit his bandwidth to a max of 60kbps/sec (which is
wonderful)  but somehow
its also limiting our samba traffic to 60kbp/sec also (we only notice it
in one direction
also (from our server 192.168.0.1 (eth1 interface ip) -> any of our ip's
192.168.0.x).
Any idea why it seems to be applying this rule to everyones traffic as
it leaves the server on eth1 ? 
We seem to have full internet download bandwidth (which would be traffic
on eth0(about 300k/s) but 
no internal traffic only passing thru eth1.
