One of the differences between a hosted Mac and one you might host in your home is in the area of routing and port forwarding. In a typical home set up you usually have a router that serves as a physical hard drive and handles all of your port forwarding duties to allow certain services in and out of your network. On a hosted Mac we open all of the ports up since we don’t know what services you want to run. As a result, instead of having a router serve as a firewall, we encourage you to use a software firewall to close the ports you don’t want exposed and to manage the port forwarding on your server. In this screencast I cover:
- The basics of security and port forwarding on a hosted Mac.
- How Mavericks handles the firewall in OS X Server.
- How to set up the Application Firewall using the built in firewall application inside System Preferences.
