First, you need to know your IP direction (the one on the computer on which you are going to create the game). In order to do this, go to Start -> All Programs -> Accessories -> Windows Command Prompt. Once there, a black window will appear. Type "ipconfig" in it and press Enter.
A lot of information will appear, but we're just looking for your IP address (or IPv4, depending on the Windows version you are using). If several connections appear, make sure to choose the one which you are going to use to connect to the other PC (e.g., if you're using a wireless connection, it's not under "Local area network", as that would be for a wired connection). Anyway, if the game doesn't work and you had multiple connections to choose, then make sure to try a different IP direction.
Once you know your IP, the rest is very simple:
- Click on Create Online.
- On the "crear partida online" window (it looks like it hasn't been translated), make sure to uncheck the "internet/lan" option so that it is shown in red rather than green.
Once you have done this, it should be working. In order to connect to the game you have just created, just open the game and click on Join Online. Once there, write the other computer's IP followed by a colon and the number of the port you've used (e.g. 6500). For instance, if your IP was 192.168.1.33, you should write 192.168.1.33:6500. Then clic on "next", on the bottom right corner, and that's it.
If you have any additional problems, please let me know. But I think this should cover it.
