+4Hello,
Might be a weird request, but I am looking to block all incoming and outgoing connections from a specific application through a specific interface (like VPN). If anyone is familiar with Windows you can do this by application over the interface. I am looking to do the similar.
Any way to do this?
+15Mac has an application level firewall (ALF) in System Preferences -> Firewall. It does have a command line to configure as well. I haven't used it myself, but here's a weblink to get you started.

+4Unfortunately, this isn't as granular as I would like and you can only block incoming connections. I know macOS uses PF now and I am currently researching how to use that since it is a little more complex.
