Hi
i'm running a video server using vlc, the video server do multicast in
239.x.x.x port 11111, here everything is ok, the streaming is reached
in a stb amino, and i can get the streaming directly to my tv without
problems, but when i try to get the streaming outside my LAN can't get
it, i do port trigger to 11111 in the router, and in the stb i use
igmp://mywanipaddress:11111, i tried to do a port forwarding, but my
router (Linksys BEFW11S4) only let me do port forwarding to 192.168.x.x
address, that's why i decided to do a port trigger, can anyboy tell me
what am i doing wrong?, thanks

That's a unicast address, it want's the multicast address the video is being
sent to.

You are applying unicast concepts to multicast traffic, NAT is
useless/impossible for multicast addresses. The use multicast on the
internet requires:

A public IP address for the sender.
A multicast supporting ISP, or a tunnel to somewhere that does.
All routers used to support multicast.

If this is for private use I suggest you stick to unicast IP.
