Linux Airwall Linux Agent or macOS Airwall Agent interface selection
The Airwall Linux Agent and macOS Airwall Agent implement an interface auto-selection method. When you first install the Airwall Agent, Linux or macOS determines the default gateway of the host and uses the associated network interface.
Note: Auto-selection is per profile.
Troubleshooting
If your macOS Airwall Agent is reporting as online, but does not seem to be working, check that the correct network interface is selected in the profile. See Setting your preferred network in the macOS Airwall Agent (HIPclient-OSX).
