Connecting to Readerware database from mobile device

There appears to some ambiguity regarding the term mobile access.  Users forward ports through their router so that devices on the internet can connect to resources on the local LAN (whether those remote devices are computers, laptops, cell phones, etc. etc. is not relevant.  mobile generally refers to "somewhere else.")

There are two  important steps in allowing access to a device on the LAN:

1. Verify that the device can be accessed from the LAN.  i.e. if another device on the same LAN cannot access the resource, then there is no point attempting to access it remotely.
   In this case, it appears that the device at 192.168.1.36 is not able to access the server at 182.168.1.33 when both are on the Orbi LAN.  That issue needs to be resolved before attempting access remotely. Windows Defender Firewall is the obvious place to start.  Firewall has different settings for public and private networks.
2. Ensure that the Orbi router has a public IP address.  If the Orbi is "behind" another router and does not connect directly to the internet, then port forwarding has no effect because connections cannot reach the Orbi.

And, yes, if port 9020 is the only port required, then that is the only port to forward.
