I would like for the Deco to keep providing WiFI. I have successfully set up Wireguard VPN server on the Brume 2 which is the main reason I purchased it but I now would like to take advantage of it's other features. The plan is also to purchase a second one for my home in the Philippines so I can link both networks.
If my proposed config is possible, will the remote access of my Emby server still function if I forwarded the port?
In my setup I have the brume 2 connect directly to the Ethernet switch and run it in drop-in mode and I'm able to still use the dhcp server provided by the router and still utilize all the functionality of the brume 2..... WireGuard, Adguard, etc.... as long as I configure routers dhcp lan service to point at the Brume 2 for gateway and dns addresses.
To clarify, is the Brume 2 in your network the first router that your Internet is connected to?
Since I have a FTTP connection, I have tried the following configuration which did not work as all my devices lost Internet access although I was able to connect to the Brume 2 via Wireguard:
