Hi, searching ML archives I found that "RTP can be matched on using
"-m helper --helper sip", so I tried the following simple rule on my router:
iptables -t mangle -A FORWARD -m helper --helper sip -j CLASSIFY --set-class 1:1
but it doesn't match any RTP traffic (no packet classified).
I tried different nf_conntrack_sip module parameters but it didn't help.
Moreover, the nf_conntrack_sip (the module that should match SIP & RTP protocols)
is not loaded by iptables.. so now I wonder how does nf_conntrack_sip work.
Any idea? Am I missing something?
Thanks,
