NOTE: RoR will not, I repeat WILL NOT use the hamachi IP. Thats because you didn't open it! Ignore that too! Because you don't have to! You also will notice that your Port for 11100 will still be closed. Now, when you host, It will STILL think you are using your actual IP, So ignore that. Launch up RoR and start up under Online Co-op game. (Free networks only allow 5 people per network including the host, I don't not know if there is a limit to how many networks one can make though.) Once you have you network created you should be good to go! (Plus, when logged in on the website for your networks, you can set them to where you have to manually allow people in, I will not be going over how to do that though.)
Remeber, If someone else wants to join, that have to know both the Name and Password to join. Name your network and set a password, If you already scared of open a port, might as well password protect the Network too. To create a network, go to the Network tab and click 'Create a New Network' Your Hamachi should be empty with no networks unlike the example I showed with 3.
So, If you are the host, you will need to first create a network.
