VPN Routing network no connection to server-side LAN

[mrmarkuz (Markus Neuberger)]

You won’t need a custom firewall rule for openvpn, it should be setup automatically.

Did you setup the static route on the router to destination network 10.8.0.0/255.255.255.0 via gateway 10.23.0.3 ?

What are static routes and how do they work with my NETGEAR router?

So the problem is actually that with PC3 (vpn client)

Which vpn client do you use on which OS?
