When access control lists (ACLs) are configured using a fully qualified domain name (FQDN), ACLs can be applied based on the destination domain name. The destination domain name is then resolved to an IP address, which is provided to the client as a part of the DNS response.
Guest users can log in using web authentication with a parameter map that consists of an FQDN ACL name.
On the
page, you can create FQDN ACLs and map them to domain lists.
