Well, I was not using the correct field. I hadn't paid close enough
attention, I should have selected 0xb8. So I am certain that is the
correct value to use for DiffServ's EF. In any event 3.0STABLE26 set
the packet properly whether I picked 0x46 or 0xb8, and with 3.2.0.17
using a packet sniffer I only see the TOS at 0x0. So it isn't setting
anything.

I had also tried using something simple, like "clientside_tos 0xb8 all"
(which under 3.0 definitely tagged all traffic) and it did nothing under
3.2.0.17.

Sorry, I 'm not familiar with netfilter and what the proper hex value
would be.

Thanks,
Brian
