I have an XPProSP2 pc connected to the internet via a wireless Belkin F5D7230v4_UK_6.00.21 router. This single pc is connected via a wire because I have a shoutcast server on this computer. The router is connected to the internet through a Speedtouch DSL modem.
In the firewall (virtual servers) of the router I have opened all the required ports for Shoutcast properly. I boot up the server (GUI version) and connect with winamp and start streaming. At first everything works fine. I get added to YP and all that jazz. Then SUDDENLY for some reason everyone is disconnected, my website script can no longer grab information from the server yet the GUI just keeps playing. I don't get touched by YP anylonger though. When I disconnect and reconnect I get the usual NAK firewall error "Can't see your computer from the outside world" and everything. Rebooting won't work either. I have to wait for like an hour before I can continue streaming again. Meanwhile the normal internet works nevertheless, and rebooting the router doesn't seem to make a difference either. If I turn off the firewall nothing happens either.
The Windows Firewall is turned off and the firewall in the modem inherits all port forwarding.
What the heck is going on?
