Bug Description
We are pushing routes from our OpenVPN server as follows:
push "route 203.0.113.0 255.255.255.0"
push "route 203.0.113.64 255.255.255.248 net_gateway"
i.e. we want 203.0.113.0/24 routed through the VPN tunnel but not 203.0.113.64/29 which shoould be routed via the default gateway of the client.
The client does not set a default route through the VPN tunnel.
When running openvpn from the command line everything works as expected, a separate route for 203.0.113.64/29 is created.
With NetworkManager odd behaviour is observed:
The default gateway (e.g. 192.168.1.1) gets a host route through the tunnel. In the end that disables all network traffic because OpenVPN is not able to route its own packets.
Something in the combination of OpenVPN and NetworkManager gets confused when it sees a route pushed with "net_gateway".
