Yes indeed.
and I Meant conntrack and connmark...
VOIP and STREAMING are beasts!!!
There are modules which analyze them and also recognize them but you
will need to enable them first.
The issue is not UDP by itself as you understand.
It's a well known issue with multi IP nat machines in ISPS.
In many cases a SIP proxy helps to fix couple things.
I haven't tried it yet but it seems like there are commercial products
that implement these SIP proxy.
