[Live-devel] live-devel Digest, Vol 47, Issue 15

[Ross Finlayson]

The bottom line here is that you cannot run a RTSP server behind a 
NAT, unless you are satisfied with accessing the server's streams 
using RTP-over-TCP only.

The IETF is currently working on standardizing techniques (probably 
based on ICE) that may allow RTSP servers behind a NAT to work, and 
if/when this is standardized, we will likely implement it.  Until 
that time, however, you should run publically-accessible RTSP servers 
on real, public IP addresses.
