Hi!
I'm building a firewall/traffic shaper using tc and connmark but I note
a strange behaviour.
Configuration:
eth0 - lan interface - rate 600kbit/s connection with mark X (download)
eth1 - wan interface - rate 600kbit/s connection with mark X (upload)
Starting a single connection (upload or download) traffic is limited
correctly but if I start two connection (one in upload and the other in
download) I note that the one in upload runs correctly (how in the
previous test) but the one in download stalls and then send some packets
and then stalls alternatively.
I don't understand why!
always (and only) the download connection has this behaviour.
two connection have the same mark (in netfilter table), is it a problem
for the shaper?
also I think about ack packets but they have a very short size (66
bytes) so I believe they are not the cause for this problem.
thanks in advance,
Fabio Marcone
