To host a reddit uhc minecraft server there are a few ways to allow your friends to connect. I was trying to show you an easy way like simple port forward, but I will run through the hard way. Open a new tab in your browser and type 192.168.1.1 in the url bar. Then, type the username and password. "The Default Netgear WNR2000v2 Router Username is: admin
The Default Netgear WNR2000v2 Router Password is: password
Click the Port Forwarding / Port Triggering link near the left of the page.
Select port forwarding not port trigger.
Click the Add Custom Service button near the bottom of the page.
Change the start and end port to 25565."
Then google "ip". Put the ip into the server ip address box.
