address for endpoints accessing from the corporate network. Note that if you are using:
- a single gateway, the authentication proxy FQDN is the
<single gateway FQDN>
- multiple gateways behind a load balancer, authentication proxy FQDN is the
<load balancer FQDN>
- a single gateway, the authentication proxy FQDN is the
