I've seen a lot of topics on forwarding ports on a Windows based OS... but what about a Mac? Does anyone know a very detailed step by step process to do port forwarding for the Mac version of Blockland?
It should be essentially the same, just connect to your router's IP in Safari. I don't have a Mac, but you should be able to find the IP of your computer and router in the System Preferences->Network->TCP/IP.
Post a screenshot of that section.
