VOD and NAT

[johnnylq]

Hello developers..

Well I'm not a programmer, but I'd like to develop a little system for
both NAT and VLC(vod enviroment) can work together without
problems....and well first I'd like to have control over the
ports(UDP) that VOD module generate before begin the streaming in
RTP....and how this module communicates to VLC-client that port; I
know that they are 2 ports(one for video and another for audio), and
use the SDP protocol......
Can you help me??? which archives I need to modify????
Thanks in advance
