You mean, you would like to have a configuration option in your VPN "connection", so that when activating another specific VPN connection, the former gets automatically disconnected? No, NetworkManager doesn't have a concept of ~conflicting~ connections. When you activate connection A, you'd have to manually disconnect connection B. > I've made the change to no success to > /etc/NetworkManager/VPN/openvpn-service.name > supports-multiple-connections=false > Yet it still connects multiple locations without disconnecting the > previous connection. That shouldn't happen. Did you restart NM after changing the file? But I suspect the file /etc/NetworkManager/VPN/openvpn-service.name is ignored and instead it uses /usr/lib/NetworkManager/VPN/openvpn- service.name. The file in /etc only exists for backward compatibility, in 1.2, the location of this file moved to /usr/lib. Changing supports-multiple-connection=false actually should give you the conflicting behavior, but that doesn't sound like the right approach. First of all, openvpn-service.name is not user-configuration. This setting is here to tell NetworkManager that this plugin is new enough to support multiple activations of Openvpn connections (simultaneously). It's not here to implement ~conflicting connections~. Before 1.2, VPN plugins did not support to activate more then once at a time. Old plugins were always supports-multiple-connections=false. > Furthermore, I've set it to specifically use tun0 for my connections > yet upon trying to load another connection even after "disabling" the > VPN (I use Cinnamon Desktop) it says that it cannot access tun0 as > the device is busy.
