Connecting with OpenVPN to RBK50 on secondary home lan

I have been using openvpn for a few years now to connect to my home network through openvpn.  I recently changed my ISP from cable (where my Orbi was my primary router) to Fios.  With my current setup I have the FIOS router as my primary router and have the Orbi connected to LAN port 1 on the FIOS router with a different subnet to create a separate LAN.   

 

Fios Gateway 192.168.1.1

Orbi Gateway 192.168.2.1

 

In the OpenVPN client.ovpn file I'm connecting to the new FIOS WAN ip with DynamicDNS with port 12974. 

 

remote XXXXXXX.mynetgear.com 12974

 

Since FIOS is the main router and I need to pass through that network to get to the orbi, what needs to be done in the FIOS router to pass the traffic?  Do I need to setup port forwarding for port 12974 and send it to my orbi?   

 

I know it's an odd setup but the FIOS router doesn't support OpenVPN so I need to pass though it and connect to the Orbi mesh network instead.   Any help would be appreciated.

    Exactly.  I am not certain what happens to DDNS.  Orbi won't configure OpenVPN unless the customer has enabled DDNS using one of the three DDNS providers that Orbi has code to support their update mechanism.  (it is a bit humbling to realize how many topics I have no knowledge of)  My understanding is that the Orbi checks in with the DDNS provider and updates the hostname with the current public IP address.  I do not know if this at regular intervals, or when the Orbi detects a change in the public IP. In your case, the Orbi doesn't know the public IP address.  You may have to do this manually.
