Block all outbound traffic except for a few ports

[DatOneLefty]

How can I set the firewall for one VM to block all outbound traffic except for a few ports? Im trying to give someone a VPS but I want to keep it from seeing my local network. I would prefer to do this using the website, but I can use the command line for the server if needed

Hi,

see this manual.

The most settings can be done on the GUI.
