Configuration of Windows Vista Media Center with Xbox on Router

I am using Windows Vista here. Media Center is running on the same. There is a router connected to the network. Also the firewall is turned on. I had connected a Xbox also on the network. And it is detected well. I can connect to Xbox live. So that means that the network is active and I can use internet. I added a extender to the network. When I checked inside the extender was not detected. It is a UPnP device. So it should be detected at connectivity. In the router setup everything is enabled. But still Xbox fails to stream the content. I had contacted my friend who was aware about the setup and he also does not understand problem behind that.

It is better if you forward a port in the router. After forwarding you would be able to access your files freely. The video streaming will work. You have to configure the settings directly in the router itself. Once the Xbox gets a dedicated port your would be able to share the media content and view your files. Turn of the firewall if needed.

I think I had gone with the settings before also. But somehow it still failed to work. I think port forwarding can help here. But yet I had not tested. There is no guarantee that after port forwarding the media files will be able to work properly. There can be some internal problem with configuration but it will be solved. I need a appropriate guide that can give me a proper step wise detail in configuration of xbox on a common network.

I got the issue on Linksys BEFSR41 router. I cannot understand that this is a router problem. I had forwarded a dedicated port to access xbox files properly on Windows Vista. But when I try to stream some content sometime there is nothing detected. It looks like having some kind of loose connection. I am on a wifi network and I cannot disable firewall. It will not be better for me. I am trying to find some solution that can put minimum changes on my security settings.

These ports should be opened in your PC's firewall. There is no need to modify any port settings on your router xbox router (because the PC and Xbox should both be on the LAN side of your router, the router's firewall does not come into play)
