How To Have Multiple Servers On One IP

Just a quick tutorial on how to get multiple servers from one router/ip, lets go straight into it:

Just To Clarify

The port 25565 is NOT the only port you can use for Minecraft, this is the DEFAULT port for Minecraft, not the only one. So aslong as a port isn't used, it can be used for anything, currently im using port 25566 for my second server. Im not going to slow down for those who dont understand what im talking about, because if you've set up one server, you should be able to do another.

Setting Up

Each router has different settings and interface, im using Netgear, and if your not, you'll have to figure out what to do on your router yourself. Anyway, log into your router and go into services (or whatever its called on your router) and create a new service. Call it something easy (say Minecraft2) and make the start and finish port a unused port of your choice, to make the tutorial easier im personally going to be using port 25567, make the type TCP/UDP and the start and finish port 25567. Heres a picture:

Now go into your Firewall Rules and add another Outbound Service, select the service you just created, and select Allow Always, leave everything else blank. Heres a picture:

Now create a inbound service, select the service you created, and put in 'Send To Lan Server' as 192.168.0.1, which should be your routers ip, if your routers ip is different then 192..., then thats up to you to fix, because if you've created one server, you know what your doing. Leave everything else blank. Heres a picture:

Now create ANOTHER inbound service, do the same as before, except this time put in 192.168.0.X, this is your ipv4 adress, the x can vary. To find out your computers ipv4 adress simply use google. Now click apply and you should be ready to create a server!

Creating The Server

Now you need to create the server, create a folder and call it whatever you want, say 'Minecraft4'. In there download minecraft_server.jar ( www.minecraft.net/download.jsp ) and put it in the folder and run it. Automatically it will create server preferences and it will give you an error, saying 25565 is already in use, this is supposed to happen. Stop the server and go into server props and change the port to your chosen port (in my case 25567), heres a picture:

Now reopen minecraft_server and it should automatically create the files needed for your server (world, op etc.).

Logging In

Finally log in to your server using your own computers ip (you can find this out on whatsmyip.org) then put :25567 after it, i.e 12.34.567.890:25567. You MUST have the port infront of it, due to the fact that you already have two servers, and minecraft will get confused with to two. Now all thats left to do is expand your server and share it, have fun!
