Hi all, it's not clear to me whether nf_conntrack_sip does SIP and RTP connection
tracking or just SIP.. can you clarify?
I need to match both SIP and RTP packets and I was wondering if the rule
below would satisfy my requirements:

iptables -t mangle -A FORWARD -o eth0 -m helper --helper sip -j CLASSIFY --set-class 1:1


Thank you,

Almost, this will match on RTP packets and incoming signalling
connections (-m helper matches on expected connections). What's
missing is the original signalling connection on port 5060.

So there is no way to identify it based on NEW connection state ?

(... Want to route new SIP calls to different locations .... )
