new OpenVPN Instances Client doesnt set IPv4 Gateway IP

[Wired Life]

Hey, is it a Bug or a Feature, when i configure the new Instances Client to likely the same (persist-remote-ip, remote-random, route-noexec, route-nopull, some other Parameters are missing)
as the legacy, it doesnt set a IPv4 Gateway IP on the assigned OpenVPN Client Interface.
The legacy Client does.
Is there a way to enable this? Because the OpenVPN Server has changing Gateway IPs.
