In the layer7 filter the examples don't use CONNMARK like with ipp2p, but I 
will try to add CONNMARK to my rules, and see what happens.

I've checked this with tc -s class show dev eth1, and I see almost all the 
traffic going to the p2p class, right now I will add a new ACK rule, to match 
ack packets, since someone told me that might be the problem.

Thanks for your interest, I'll check your rules right now, to see if that 
helps.
