Accessing office private network via Openvpn on Opnsense fiewall

[mohanjoy]

Dear Team,

I have configured OpenVPN on an OpnSense firewall server with the public IP address 11.121.XXXX. Additionally, I've set up a private networks on this LAN: 192.168.21.1.The OpnSense firewall is a separate hardware unit.

Furthermore, I've deployed a separate OpenSUSE router with the public IP address 2.195.XXXX. On this router, I've configured the LAN IP as 192.168.100.1, which serves as the internal system network access point. Currently, I'm able to access the router's private network via OpenVPN from an external network. Please check the attached network diagram screenshot.

Could you provide guidance on refining these configurations?

Thank you
