Most all Allonis myServer 6 systems use TeamViewer software to allow Allonis to remotely connect to the system via the Internet.
Certainly the system has to be exposed to the Internet for our remote assistance.
No External website URL is required to be setup.
Here are details on what ports TeamViewer uses for Corporate networks.
Most all networks have no issue for TeamViewer to work.

Installing TeamViewer on Windows
Sometimes it is needed for Allonis to use an on site Windows PC (like a laptop) to diagnose or configure a system remotely.
From that Windows computer, install TeamViewer HOST software

Once installed, provide Allonis with the TeamViewer ID and temporary password. Note that the temporary password changes with each computer reboot. So, update Allonis with what the password currently is, or set the password to be permanent. You can always change those settings after Allonis is finished using that laptop.
Reset TeamViewer licensing (not to be used):
sudo teamviewer daemon stop
sudo rm /opt/teamviewer/config/global.conf
sudo teamviewer daemon start
Wayland
Raspberry OS later updates suggests users switch the Raspberry desktop to use "Wayland". However, this is not compatible with TeamViewer. Post the OS update, the next reboot will ask if you want to switch to Wayland. Always click "X Org" and NOT Wayland. However, if you do select Wayland, here is how you can change it back to X Org from the Raspberry Terminal window (available in myServer's Terminal window too):
$ sudo raspi-config
Select A6 Wayland
Select X11
ok→finish→reboot
