if you loosing the admin interface, i think as first option is to tick the auto log out because by default after 5-10 min it does log out and need to log back in each time, guessing you are trying remotely could be more complicate
If you enable bind ip to mac you need to register your devices (give static ip) ... in this case you may need at System Maintenance >> Management >> to register up 3 devices at the list where can access the interface
(Access List from the Internet)
... but for me i don't use servers,vpn, port forward etc ... with bind ip enable it works with out enable this feature and i have access to the interface each time
If you enable strict bind ... and you add devices at the right window, they will have access to the internet but other non register not
If you have not add or register any devices at the right window then no one will have access to the internet
