Why can’t people see my game?
War for the Overworld operates on a peer to peer architecture, when you host a game your server is advertised on Steam’s Master Server and players locate it via that but they connect direct to you.

In order for other players to see and join your game you will need to open ports which will allow data from the internet to flow into your network and to your computer specifically on those ports. This is common to any game where you host the server yourself i.e. Minecraft. The process of opening these ports is known as port forwarding.


But isn’t that risky?
By it’s nature you are opening holes in your router’s firewall, your first line of defense. Doing something like that is taking a risk but only if it is mismanaged, while it’s easy to imagine that someone could use this new door to steal all your personal information it’s not quite as simple.

Traffic that goes to a port is only picked up if something is listening for it, your PC will ignore any data coming in on that port unless there’s some form of application listening (In this case WFTO) when WFTO isn’t there the data will simply be dropped.

That’s not to say there aren’t other risks and while the chance you encounter any problems is minor we still recommend that once you’ve played your game you disable the port forwarding.


Can’t you do this automatically?
WFTO tries to automatically open the necessary ports on your router via a process known as NAT Punching (also as Universal Plug and Play) sadly this protocol is not supported on a great deal of routers and itself is aged and unreliable. This means it can’t always open up ports on some routers, requiring some manual assistance.

When WFTO tries to open ports it only opens ports 27015 and 27016, two standard steam ports.


A guide to Port Forwarding.

Welcome Underlord, this guide should provide you with sufficient information for you to successfully port forward, allowing you to invite friend and foe alike into your battlegrounds.

This information will vary from router to router and hence can not guarantee that this method will be accurate for you, but we will provide as much information as we can to help you on your way to getting in game as smoothly as possible.


Common Terms

Before we begin I will briefly explain terms that you may encounter while you go through the port forwarding process

IP Address - Your IP Address is the unique address that identifies your device on the network. There are two types of IP Address:
  • Local - typically identified within the 192.168.x.x range which identifies devices on your network
  • Global - which identifies your Router and your network on the internet, this is typically assigned by your internet provider.
Default Gateway - A default gateway is the Internal IP address of your router.

TCP & UDP - Are different kinds of ports which handle different tasks. Generally UDP handles faster transmissions for real-time applications such as gaming, video etc. All Network devices have lots of these, they are used to help identify an internal network device to the internet.

  1. Get your IP Addresses

Let’s begin by finding out what your default gateway address is, this will give you access to the internal setup of your router and this will be where the magic will happen. We’ll also get your IP Address at the same time as you’ll be needing this later.

  1. Open your start menu
  2. Enter cmd.exe into your search bar and launch the cmd.exe application.
  3. You will see a black screen with white text, This is known as command prompt.
  4. Type the word “ipconfig” into this box and hit enter, this should give you an output that looks like this
  5. Now to identify your ipv4 address and default gateway, depending on how your computer is connected to the network you will have to look for either “Ethernet Adapter” or “Wireless Adapter”
  6. From the appropriate adapter pick out your IP Address and Default Gateway, note these down.
2. Find out more about your Router
There’s a huge range of different Router’s out there and sadly this means that there’s no set way for you to port forward. It’d be impossible for us to cover every possible variation of Router so we can only advise that you head on over to portforward.com and look up your Router’s model.

You can usually find your Router’s make and model simply by looking at it, usually the manufacturer will place a sticker with both their name and the model in question somewhere on the Router.

If you can’t find that try entering your default gateway address into your web browser this should allow you to connect to the router and scour it’s interface for information.

Once you’ve discovered the make and model be sure to look it up on portforward.com for specific port forwarding instructions.


3. Connect to Router and Forward Ports

Once you’ve confirmed how to port forward via portforward.com there’s not much more that we can teach you here. You’ll simply need to connect to your router on your default gateway address and then follow the instructions provided to you.

Forward the ports 27015 and 27016 to your computer and voilla you’re done! With that your games should now be visible on the Multiplayer lobby and ready to join!

An addition to the above:


Static and dynamic IP-addresses
You may find that after restarting your PC, the local IP address found in step 1 has changed. This means your IP is dynamic: it is automatically obtained from your router, and may change every now and then. Especially with multiple PC's on the network, the IP addresses may be scrambled every day.

When the IP address changes, this means that the ports are now forwarded to the wrong IP, and it won't work anymore.
You will have to find the new IP and change it to that.

However, it is also possible to change your IP address into a static IP, so that your PC will always request the same IP from the router, and your forwarding stays intact.
For more information on how to do that, visit these guides on portforward.com/networking/staticip.htm


Firewalls
This one may speak for itself, but a firewall running on your PC also blocks ports. Make sure that you allow WftO in your firewall. Most firewalls pop up an "allow/deny" dialog which allows you to let the program accept connections.
In some cases it may be necessary to explicitly add WftO to a whitelist.

tried it and failed, made rules in firewall and router - no dice
made all firewalls (AVG and windows firewall) go sleepy sleepy - no dice
tried running in admin mode - no dice
used a payed version of portforward - no dice
tried any combo of the above - no dice

now i dont know what the deal is, ive got a fair ammount of knowledge on computers and its workings but this is rediculus.. all im trying is being able to set up multiplayer games since most ppl cant.. i wanna test stuff etc.. however with this whole opening a port thing idk what else to do, occording to portforward my ports to 27015 and 27016 are open so why cant a freaking host games?!

-- so i managed to finally get it working, i now have ecceptions on both udp and tcm.. i own a apple airport extreme so for those who run into the same issue as i have send me a pm and ill explain it for you

Did you, by any chance, have had an old computer at the same modem before for wich you used the same PC name? because I had this issue once and solved it by simply renaming my PC in windows, so my Router actually recognized the correct machine.

i have new parts and all but no the issue wasnt name since the name was diffrent this time around.. the issue was: while opening the ports i expected to have TCP and UDP at the same time but it only made TCP ports, so i had to edit in the UDP ones in seperately

This is outdated, the programm to set it up costs 30$ and im not willing to pay that just for the multiplayer feature.

can you please update the guide?

What I heard it still does work, further to it's free to do, because you can do it yourselfe.
Further to you can now use Hamachi if you don't want to do that.
