How can I block all incoming/outgoing internet traffic except streaming to an Xbox 360?

For the past few weeks, streaming video files from my PC to my Xbox 360 has started failing, with the videos pausing to (presumably) buffer, and then continuing only to pause again a short time later, making the videos unwatchable.

This never happened before and I can only assume something else on my PC (which has many background and foreground programs open at any one time) is competing with the bandwidth.

No other PC or device is connected on the internal network and everything is where it's always been.

That's why I want to try blocking all incoming and outgoing traffic on my PC except the streaming to my Xbox.

Are you streaming from your PC or from the Internet? Or does your PC need to use the Internet to reach the Xbox? That's pretty unusual -- aren't they in the same location? – David Schwartz Feb 4 '14 at 21:34
@DavidSchwartz: I'm streaming locally and wireleslly from PC to Xbox. They are each in separate rooms. – ProgrammerGirl Feb 5 '14 at 0:42
So just pull out your Internet connection. – David Schwartz Feb 5 '14 at 1:24
@DavidSchwartz: I'm trying to figure out a way to do just that with the Windows Firewall. – ProgrammerGirl Feb 5 '14 at 1:46
Let in all traffic with both local source IPs and local destination IPs, block all other traffic. – David Schwartz Feb 5 '14 at 2:45

Find out what port you are using to stream to the X-Box and configure the windows firewall to only allow traffic over that port.

You can open the firewall settings by typing in wf.msc into the search box on the start menu.

How can I find out which port my Xbox 360 uses to stream? I haven't configured any special settings, so it should be the default ones, I'm just not sure what those are. – ProgrammerGirl Feb 4 '14 at 22:08
Here is a list of all the ports that the X-Box uses. – Alex McKenzie Feb 4 '14 at 22:15
Are you on a wireless connection, or are they both wired? – Alex McKenzie Feb 4 '14 at 22:15
I'm streaming wireleslly. Your link is a pretty big list, is there a simpler way to do this, or is my only option to block all traffic except all the ports listed in your link? – ProgrammerGirl Feb 5 '14 at 0:43
I think that your wireless connection isn't fast enough. It is possible for your wireless speed to drop due to more interference or the router overheating. Here is how to check the speed on your computer. I don't know how to check it on your XBox – Alex McKenzie Feb 5 '14 at 3:33
