Lately, I had an issue with routes, because I wanted to use my VPN connection only for resources on network that I wil connect. Unfortunately in Fedora 19 this option: “Use this connection only for resources on its network” doesn’t work. However there is workaround (from RedHat bugzilla):
Just use this tool (of course as root in CLI):
You will find there this option – just activate it, and it will work.
Changing settings to Your VPN connection under nm-connection-editor will couse that this connection will disappear from Network Manager settings, but It will be accessible from Newtork Manager icon in the upper right corner of Your screen. You will be abble to connect to this VPN through Network Manager applet.
