Hello,
Is there an easy way to match RTP/UDP traffic?
Thanks.
Francois.

If you mean RDP / UDP, then it's easy:
iptables -A FORWARD -p rdp -s a.b.c.d -d w.x.y.z -j ACCEPT
iptables -A FORWARD -p udp -s a.b.c.d -d w.x.y.z -j DROP
etc....
If you didn't mean RDP, can you give us a reference to tell us what RTP is ?

RTP (Real Time Protocol) is used for example with SIP for VoIP traffic.
Is it possible to match it with iptables?
Thanks
Francois.

From your original posting I assume it works over UDP; what port numbers does
it use ?

Hi Francois,
Once upon a time I wrote a module for RTP. Its not up to date with
netfilter and somewhat experimental but you can try it:

Cheers,
