Hello lists. I have strange issue with KDE NetworkManager on Debian Unstable (Stretch). I'm using openvpn connection, and routes from OpenVPN server are not pushed into NetworkManager.
So I've tried configuring static route. The problem is that NetworkManager ignores routes with 255.255.240.0 netmask. If I use 255.255.224.0 or 255.255.248.0 masks - static routes are created as soon as i connect to vpn server. But it fails to create a route with 255.255.240.0 mask. Any ideas? Thank you.
