About FQDN Gateways (Legacy Egress FQDN Filtering)
An FQDN gateway (Legacy) is created after you add a tag that contains URLs that are allowed or denied to a Spoke Gateway in the Egress Control Filter workflow. The gateway is then added to the Egress Gateway View on the Controller > Security > Egress Control tab.
From here you can select an FQDN gateway and:
-
Detach/disable FQDN: disable FQDN function for the gateway.
-
Remove tag: remove a specific tag associated with an FQDN tag.
-
Download logs: download a log for the selected gateway.
-
Edit Pass-through: specify traffic from one or more subnets to only be NATed and to bypass the FDQN filter function.
