Map DDNS Servers to Regions
When setting up a VPN profile, you choose the Secure Access region where your data center is located, which determines where the VPN traffic will be routed within the your network. You also choose the DNS servers to resolve DNS requests to internet resources. Optionally, you can include DDNS (Dynamic DNS) servers in your VPN profiles to update the mappings of domain names to IP addresses when a remote user's network IP address changes.
Cisco Secure Access allows you to map DNS and DDNS servers within a VPN profile, essentially directing all your DNS requests through the VPN tunnel to those designated servers, ensuring that your internet traffic is routed through the VPN and utilizing the chosen DNS resolution service.
This topic describes how to set up a VPN profile to map the DDNS servers configured within your network to resolve DNS requests and updates so VPN clients can access network resources when connecting over VPN.
