Manage DNS Servers

Cisco Secure Access protects the DNS traffic in your organization. Add DNS servers to resolve DNS requests to internet resources. When adding these DNS servers, DNS Server 1 resolves before DNS Server 2. Provide DNS servers that could resolve both IPv4 and IPv6 if applicable.

About DNS Server Configuration

Add a DNS Server

Add an IP address or address range for a DNS server. Your DNS traffic routes through the DNS servers managed by Secure Access.

1. Navigate to Connect > End User Connectivity > Virtual Private Network and click Add IP Pool.

2. Click Add IP Pool.

3. Enter the IP pool parameters, including the required DNS Server. During the initial deployment before any IP pools have been configured, there is no DNS configuration. You must provide a valid DNS server.

   

4. Click + Add to add the initial DNS server configuration.

   1. Enter a label for the DNS server in the Name field.
   2. For DNS Server 1 provide the IP address of the primary DNS server. Optionally, if you have a secondary DNS server, add an IP address for DNS Server 2.

5. Click Save and then click Close.
