I'm streaming a radio via Shoutcast server from a PC in my office and ppl from around the world can hear it in browser or via wmedialayer/winamp, but people from my ISP (including me when I use outer IP) can't, a stream simply can't be opened in browser or winamp/wmediaplayer. What should I do?
Some ISPs do not allow routing between IPs on the same network. We had a similar issue with a small rural school where most of the town couldn't access the sit hosted at the school because they were on the same subnet.
The simplest solution is to rent a Shoutcast server from a third party and stream to that. You can find them very cheap.
