OpenVPN WAN Client - Server Initiated Traffic

Hi, I have a Balance 20 with OpenVPN WAN subscription installed and functioning well for client side initiated traffic. I am trying to allow traffic initiated from the server side LAN access to my Peplink client side LAN.

It is important to note that I can ping the client side OpenVPN Interface IP 172.16.1.2 but not anything on the client side LAN.

I have tried OpenVPN WAN settings of both NAT and IP Forwarding

I have tried port forwarding client side LAN through OpenVPN WAN no luck

I have added firewall rules to allow same

No luck.

Any insight or ideas?

Thank you,
Scott
