openVPN connection ok, but no access to LAN

[vikozo]

Hello
i have added openVPN and some mobile client do connect, but...
i wish to connect to my LAN with openVPN.

With my laptop (which is connected to the LAN) i do conect do nextcloud.
called nextcloud.mydomain.ch (is in DMZ IP Range) but this page is not available from outside (WAN).

so my idea, i should be able to connect trough openvpn --> lan --> DMZ to nextcloud.

which is not working!
i got a connection to opnSense but how to check how far it works?

have a nice day
