Orbi RBS850 VPN Client Devices Cannot Access LAN
I'm struggling to setup my VPN such that I can access the devices on my LAN. I'm using OpenVPN and No-IP for my dynamic DNS. I have downloaded the OpenVPN configuration to my phone with the sett...

It would help to know how the phone is attempting to access other devices on the LAN.
Because smartphone VPN connections are tun (Layer 3 "tunnel") rather than tap (Layer 2 "tapped into the subnet") communications that rely on LAN broadcasts may not be successful, whereas communications that specifically provide the target IP address will.

What application is being used on the smartphone?
iPhone or Android?

Thanks CrimpOn I'm using an iPhone.
I have an Amcrest camera and an Aquarium controller (GHL Profilux) on my local network. Both are assigned to a static IP address by the router. I'm not sure how to tell exactly how the respective apps are accessing the devices.
Interestingly for the Camera - I can get a response by putting the IP address directly into the browser. It isn't possible to access the feed that way (that functionality is no longer supported), but it does bring up a log in prompt - something that does not happen if you are both off the network and not on VPN. Going through the app though, I cannot access the feed as I can when I'm on the local wifi network. The app for the aquarium controller requires entering the IP address in order to make a local connection, but I'm unclear how to determine how the phone is accessing the device.
I run into a similar issue on my Mac when I VPN where I cannot access these devices. I also cannot see the other macs on the network under "network" which I can when I am on the local network.
I had VPN setup on the Orbi previously and was at that time able to access the devices. I'm not entirely sure what has changed. I accidentally let my No-IP account lapse and when I got it reinstated I set up my VPN again and it hasn't worked right since.
