+### Portforwarding doesn't work on the master server when running under WSL
+
+If you follow the ubuntu guide on WSL (Windows Subsystem for Linux, Bash on Ubuntu on Windows specifically), you will find that the website works on localhost and on your local ip, but not on the global ip. This is also true when you correctly port-forwarded the correct ports. Even when routing this server through nginx in WSL, the issue persists. Then, on a hunch, I tried to run nginx from windows itself and found that this DID work. It came to me that the only usage difference between the 2 versions of nginx is that I got a Windows Firewall popup. 
+
+TLDR: the tested fix is: 
+
+- open your windows firewall and go to advanced settings
+
+- click on inbound rules and click on new rule...
+
+- select port and click next >
+
+- select TCP and select specific local ports and type in the ports that you want to open (comma separated) and click next > 3 times
+
+- give the rule a name (like 'web server' or something), give it a description (optionally) and click finish
