connect VPN and LAN Clients

[mawu]

Hi friends ,

small problem with my vpn connection.

If I connect my phone with VPN and scan network - I only see all VPN clients.
If I connect my phone only with WLAN and scan network - I only see all LAN clients / but no VPN client.

If I want to connect Synology A with Synolgy B over the VPN tunnel - both Synologys has to be connected to the VPN Server. In Explorer or windows I can`t connect to the synology 10.8.0.2 ...

I think in my ovpn-server is an option missing - ;-)

Can you please help me

THANK U
