OpenVPN NS server-client

[mrmarkuz (Markus Neuberger)]

If Nethserver acts as your gateway it should just work. If there’s another router between www and Nethserver, you may need a static route on the router that directs your VPN network to the Nethserver.

OpenVPN client cannot see local network

I think there’s a static route missing on your router. Your router does not know about the vpn network and drops the ping.
