I have an ATP800 thats has all ports outbound blocked except for what is allowed thru the hand built security services. The UTM license is in the portal and linked to the device, but even when I try to refresh the license thru the ATP800 it will not update. I'm assuming it uses a specific port that we have blocked. does anyone know what port it is uses? and does the ATP use a specific port to get the idp and av updates? That may be blocked as well?

Thanks in advance for any guidance and help !!

    Hi @mike4682 ,

    Welcome to Zyxel community.

    Signature update on https 443 port, please confirm if tcp 443 service port is allowed on uplink router.
