Challange: Sophos xg access point is not listed on "pending access points"

XG Firewall cannot manage any other vendor access point. So what do you mean by listed on pending access points? Only Sophos based Access Point will be listed. 

the main goal is to make a wifi with a zyxel access point. 
as i saw in some descriptions, the access point should be listed in this list:

but yeah.. i read about that its possible in an other thread 

any ideas?

You can only manage Sophos Access Points with the Firewall management interface.

Any other third party access points will have to be managed on It's own interface.

This is what Devesh said, you can manage Sophos APX's within the Firewall, or use a third party standalone access point and manage It somewhere else.
