|
On Mac deletes all routes relating to a given network interface
|
|
|
|
Useful to clear stale route entries left by vpn clients such as AWS Client VPN that may interfere with networking or reconnections
|
|
|
|
(You may also need to restart your wifi after disconnecting AWS VPN Client - appears to be buggy behaviour)
