Hi all,

i have a simple question for understanding how the osx firewall works...

For example in windows, i can either enable applications, or i can enable a port.

The firewall in osx (10.11.1) only can enable some already known system services, or applications.

Does this mean ... when i enable an application, all ports the app is listening to are enabled?

Or is there an other way to enable/disable specific ports?

greetings from germany

A:

firewall port management with the OS X firewall tool is not available. It is by Application only.

If you require a firewall you will need a 3rd party app that allows port management.
