DNS and Routing Options
By default, OpenVPN automatically uses the server's settings for DNS and routing.
If you want to change these settings, go to Network > VPN > Open VPN > [Session Name] > IPv4. Here you can:
Deactivate Automatic DNS
Add Extra nameserver(s)
Add Extra search domains
Deactivate Automatic Routes
Deactivate VPN is the default route
Additionally, you can enable three custom routes in Network > VPN > Open VPN > [Session Name] > Route [0,1,2]. For each enabled route you can configure:
whether it is a Network Route or a Host Route
Network/Host IP
Network Mask (for Network Route only)
Optional: Gateway
Optional: Metric (a quality rating used for routing decisions, 0 being the best)
