Before this one, I made an instructable on how to make a server on the computer, and it got more views than I expected, so I decided to make an instructable on how to make a server on Minecraft PE. Unfortunately, as far as I know, this will only work with idevices. So my apologies for you androiders. Anyway, all you will need is your router and your idevice. You will also need to know the username and password, which is usually found on the router.
Step 1: Wi-Fi Network
First, find the Wi-Fi network you are on currently and click the blue arrow beside it. Also, you'll probably want to make this on your own Wi-Fi network, not like some McDonalds network, because, again, you'll need to know your routers information, and McDonalds probably won't hand that out. After you press that blue button, memorize your IP address and router address. You'll need these for the next step.
Step 2: Safari
Next, go on safari, and in the address bar, and type in your routers' address. You'll see a page asking you to login. Type in the username and password of your router in those blanks. Follow the video instructions. Then, find out your IP address.
Step 3: Starting the Server
Next go into any MCPE world, and type in your IP address. Give it out to some friends and all they have to do is type in your IP and they can join you. Unlike MCPC servers, if you are not playing on your server, then no one else can join. So to have people join, you will also need to be playing.
Step 4: Conclusion
