What port in router

Shouldnt need to open ports... This worked for me on å NetGear R7000 Nighthawk, could be similar on your router:

Enter WAN-setup on Wi-Fi router, and make sure "IGMP Proxying" is enabled. (in my case I had to deselect the "disable IGMP Proxying" option.
 
port 80 is the default port for a webserver unless you are running a webserver on your computer do not open any ports! i would even recommend to disable upnp if you do not need it. if you are unsure at least check your router here first, it will test if anything is open and also has a upnp test:
Code:

don't worry :) click the upper right corner to test your machine. i must say i do not especially like steve though but the test works and there is nothing to fear.

btw. upnp is not needed for this service or any streaming addons.
