Allow routes without gateway
In a scenario where the VPN connection is used for access to company network only, there needs to be a route (either pushed or configured statically) to the company network address range through the VPN connection. The gateway for such route should be the remote endpoint internal address, but it may change over time.
OpenVPN supports route <network> <mask>
with gateway omitted for this use-case. However, there is no way to configure this in NetworkManager - a route without a gateway is considered invalid and not saved.
Please add a way to specify such route.
