Step 1: Open
Open you mcpe and click on play
Step 2: Next
Click on edit and you'll see a button that says external click on that
Step 3: Now
Now you'll see this on your screen. Put in any port you see online but I chose this one. Then click add server
Step 4: Last Thing
Click on the server it should've popped up after you clicked add server. If it says it cant connect it probably means there isn't enough room right now. Now have fun playing online!
