Thanks ! Sorry for the lack of details. The goal is to access a webpage put up by the furnace.

There are two methods to access a web page hosted on a device on the local network (LAN):

• Connect to the LAN using OpenVPN and then open the web page using the IP address of the furnace device.
• Forward port 80 (http) through the router to the IP address of the furnace device.

Both of these methods require:

• That the furnace device have a predictable IP address on the LAN.  This is usually accomplished by reserving the IP address to the MAC address of the furnace Ethernet adapter in the Advanced Tab, LAN Setup Table.
• That the Orbi router is not "behind" another router.  i.e. the internet IP address of the Orbi router must be a public IP address.

Setting up OpenVPN is a bit complicated.  See page 122 of the User Manual.

Forwarding port 80 to the furnace device is done on the Advanced Tab, Advanced Menu, Port Forwarding.

Instructions for port forwarding are on page 112 of the RBR20 user manual:

You should be aware that forwarding a port through the router to a local device will result in constant attempts to connect to the device from people on the internet who discover that the port is open.  This is an unfortunate consequence of "opening the door".  For example, when I get a phone number, there is nothing I can do to prevent people from calling it.  ("To see if your home is qualified for upgrades, press 1.  If you are already qualified, press 9." -- 20 times every day!)  Once you forward a port, it is up to the furnace device to recognize allowed connections and reject unallowed connections.)
