[FFmpeg-user] ffplay can't play RTSP stream over internet (only inside LAN)

[Dâniel Fraga]

	I have some IP cameras and inside my network I can play the
RTSP stream fine. But if I try to do the same over internet, it doesn't
work. Both routers are configured correctly and I can access those IP cameras 
using other software (like IP Cam Viewer for Android):

	I asked it because I have the following setup:

COMPUTER --- LAN 1 --- INTERNET --- LAN 2 --- IP CAMERA

	Here it's the log (analyzeduration and probesize option didn't help):
