[Shorewall-users] TC issues after updating from RHEL4 to RHEL6

Hi,

I've just realized that something seems to be wrong with traffic shaping
on two systems which were running RHEL4 and are now running RHEL6. While
trying to find what is wrong I even simplified the config but it just
doesn't seem to work as it has with EL4. The test config looks like this
(eth2 is the "internet" interface):

in shorewall.conf I have:
TC_ENABLED=Internal

tcdevices:
#NUMBER: IN-BANDWITH OUT-BANDWIDTH OPTIONS REDIRECTED
#INTERFACE INTERFACES
eth2 20000kbit 2000kbit

tcclasses:
#INTERFACE:CLASS MARK RATE: CEIL PRIORITY
OPTIONS
# DMAX:UMAX
eth2 1 full/4 full 1
tcp-ack,tos-minimize-delay
eth2 2 full/4 full 2 default
eth2 3 full/8 full*8/10 2

Now, on the completely idle link I can do what I want, downloading http or
doing rsync via ssh, I get download speeds of 200-500 kB/s. Setting
TC_ENABLED=No immediately increases the downstream to its full speed.

Looks like I'm missing the obvious, but what is it?
The output of "shorewall show tc eth2" is attached.

Thanks for any ideas!

Regards,
Simon
