I have a Slate.
I use VPN Wireguard Client.
I have “Allow Access Local Network” switched ‘on’.
The instructions for my Arlo App (for viewing my camera storage outside the LAN) say to enable port forwarding, and gives the internal address of my camera server, internal and external ports.
I also went to other tab and opened port on router.
I configure exactly as it says- cannot get to work.
