Userportal access from WAN
If you manually change the default ports, we strongly recommend that you use a unique port for each service. Using a unique port ensures that services are not exposed to the WAN zone even after you turn off access.
Example: Don't use port 443 for both the user portal and SSL VPN. If you do, the user portal will remain accessible from the WAN zone when you turn off WAN access from this page.
The firewall turns off access to the user portal from all WAN sources if there aren't any successful sign-ins from the WAN zone for 90 consecutive days. This applies to all deployments. Access given to specific WAN IP addresses and networks through a Local service ACL exception rule isn't impacted. These sources will continue to have access even if there are no sign-ins.
