Hi,
Cannot find solution anywhere.

Problem:
NAS Synology server with Open VPN server on port 1194 working in subnet: 192.168.23.0/24 with ip 192.168.23.100 is behing office router (ip 192.168.0.232)



Network configuration:
Port forwarding :1194

IP: 62.148.xx.xx (open port 1194 UDP and TCP) is redirected to internal network to ip 192.168.0.232:1194 this internal IP is office router that forward port 1194 to 192.168.23.100 which is Synology NAS server with OpenVPN.

Thank You for reply.

Unfortunately the enviroment configuration website(for Synology DS) shows no logs for when trying to connect.
And what is more i do not konw how to see this server configuration . I can only enable it in the configuration website and generate client config.
Here is an example for PPTP and it looks similar for OpenVpn:
