For some people the ports just don't open for themselves.
In this case get PortMapper: http://upnp-portmapper.sourceforge.net/

Install it and start it. Then you'll get to see something like this:


Click connect.


When it's connected, click ''Create'' and make your Bloody Trapland port.


Name your port something like ''BloodyTrapland''


Then click ''Add'' and then edit your ports.

Just double click on the port parts, and put in the Bloody Trapland port (6883)
Do this for both TCP, and UDP (Click the ''Protocol'' box to change between them)

You can also add multiple ports if you click ''Add port range...''


And remove the ports you don't need (6884)


After you're done adding your ports, click save.

Then click on the port you just made, (BloodyTrapland) and click ''Use''


Now you should have port forwarded Bloody trapland!
Now you just need to make the server...

After port forwarding, you can start your server.
To do this: Start Bloody Trapland.
In Bloody Trapland, press enter (or A for Xbox controllers) to start.

Go to PLAY ONLINE (We'll go over CUSTOM LEVELS later)

Then you need to select the local players you want.
(People playing on one PC with the keyboard, and controllers)

Then finally to make the server, you select the HOST button.

And choose Mode, World, Level, and your Password (If any)

Once you've chosen what settings you want, just go and select the Start button.
Note: As host you can change level without having to close down the server. (in pause menu)

If you want an IP to give to your friends, you can use: What is my IP[www.whatismyip.com],
or just look at the external address in PortMapper. (Click "Copy" to copy it.)

Go to "CUSTOM LEVELS" and pick your local players.


If you don't have any levels. Go to the workshop, and subscribe to some.
(The levels you've subscribed to will appear on the left.)


After setting your password (if any)
Go left, then up, and down to change between subscribed/custom levels

When you've picked your level press enter. The game will then start.
Note: The game automatically makes it a server.

Re-Note: As host you can change level without having to close down the server. (in pause menu)

How to join a server (and other things):
To join a server on the list, just go left, and you can go up and down between servers.
Press enter when you found one you like, and if it has a password,
type the password (if you have it) in the box that will pop up. (to cancel press Esc)
If you want to join with an IP, select MANUAL JOIN and put in the IP.
And to refresh the server list, just go back once, and re-select your players.

What does it all mean?:
Locks next to a server means it has a password.

"Host name" is the name of the server, and the one who is hosting it.

"Mode" is what kind of mode the server is. It can be "Adventure" "Race" and "Custom"

"Level" Is what level the server is playing on.

"Players" Is how many players there are on the server. There can be 1 to 4.

Ping is how good your connection with the server is. The lower it is, the better.

Warning: You can't join servers with "---" (It might also say "---" if it's loading the ping)
And you SHOULD probably not join a server with 200+ ping.

• You can press enter to chat, and put in commands.
  
• Typing Help will show all the commands.
  
• Typing Kick (only available to the host) will kick a player (Example: Kick JacobMIX)
  
• Typing Password (only available to the host) Will change, add, or remove the password.
  (Example: Password 125, to change the password to 125 regardless of the current password.
  Type password without a followup to remove the password completely)
  
• Typing Deaths will show how many times players have died.
  
• Typing Kills will show how many times players have killed someone.
  
• Typing Wins will show how many times players have gotten to the end of a level.
  (Note: If a player leaves the server, their stats will be lost, even if he rejoins.)
  
• Press Tab[www.wpclipart.com] in multiplayer to hide the nametags.
  
• In multiplayer, you can duck, and press enter to keep ducking without having to hold down the duck button.
  
• Race multiplayer star fact: If someone beats the time limit for the star,
  everyone on the server gets the star! But only the person who beat the level gets the score.
  
• You can now also disable high ping kicking. Just pause as host, and go to options.
  Then change the "Allow high latency" to yes. (People with high ping will not get kicked)

If it still does not work:

Firewall:

Make sure you have made firewall exceptions
1. Go to Control Panel>Windows Firewall>Advanced Settings>Rules for incoming connections>New rule
2. Select Port>TCP>Specific>type '6883'>Allow connection
3. Select Port>UDP>Specific>type '6883'>Allow connection
4. Now do the same for outgoing connections

You can also add ''Bloody Trapland.exe'' if you wanna be sure.

A proxy might also cause problems. Help here[answers.oreilly.com].

If you want to. You can join this group.

Also PortMapper uses Java[ninite.com] on PC, and UPnP[en.wikipedia.org] on router.
So it might not work for everybody.

If PortMapper can't find your router. Try going into the PortMapper Settings,
and change the UPnP library. Else it might be because your router doesn't support UPnP.
