Hi, so far I have learned that I have three IPs, one public or external router which is dynamis but I turn static, the second the internal router which is 192.168.1.1 always and the third the IP of my PC which is 192.168.1.2 always. I have to forward one port in order to make routable my IP address and used for viewing a streamed video. So when I get into my router and open a port they ask me for an internal port so I wrote 192.168.1.2 (My PC IP) and a port whatever Then I write the same port in my WCM settings. But when I try to wacth from my office the windows media player show me a message,"Windows Media Player cannot play the file because a network error occurred. The server might not be available. Verify that you are connected to the network and that your proxy settings are correct." So what am I doing wrong?, please I really need help on this. Just in case I use OS Windows XP in both places in my house I have speedy 200 from telefonica and XAVI7768 router in my office I have speedy 600 from telefonica and XAVI 7768router. In my home I have 304Mb RAM memory in my PC thanks
