[Live-devel] NAT and RTCP

[Ross Finlayson]

>My hunch tells me the RTCP ports are dynamically set by the stack

Yes, however, the RTP and RTCP ports start at 6970 by default (see 
"liveMedia/include/OnDemandServerMediaSubsession.hh").  (I chose that 
number because other servers - e.g., Apple's - use the same number.) 
RTP ports are always even (so, 6970, 6972, 6974, ...), and RTCP ports 
are always odd (so, 6971, 6973, 6975, ...).

If you have a limit on how many concurrent streams you may be serving 
at once, you may be able to arrange port forwarding just for a small 
rance of ports, starting at 6970.
