How to tell which interface is being used?

JackO

New to open VPN.

In Windows 10, is there a way to tell which interface in system is being used by OpenVPN and tap adapter?

I have systems with multiple physical interfaces installed. Does OpenVPN and tap adapter always bind to the interface with the lowest interface metric or with the default gateway address 0.0.0.0/1 in the route table?

The Iface column in the line with destination default tells you which interface is used. Running ifconfig will give you the information you need. You can also use the IP addr command and any inactive interfaces will be designated as having: NO-CARRIER.
