DNS Forwarders Test Virtual Appliance Deployments

Last updated: Aug 07, 2025

Test Virtual Appliance Deployments

After you deploy the Cisco Secure Access Virtual Appliances (VAs) in your environment and set up internal domains in Secure Access, we recommend that you test your Virtual Appliances.

To begin enforcing your DNS-layer security settings, DNS traffic from the endpoints on your network must exclusively use the VAs as a DNS forwarder.
