Using Certificate Authorities
You must use obtain and install a CA certificate on each VPN member to authenticate
the local device certificates on your managed devices.
Configuring Certificate Authorities
After you have obtained a CA Certificate file (.cer) from your CA, use this file to create a
Certificate Authority object. In Object Manager, select Certificate Authorities, then click
the Add icon to display the New CA Certificate dialog box. Enter a name for the CA
Certificate, then click Load CA certificate and load the appropriate .cer file. NSM uses
the information in the .cer file to automatically complete the Subject Name, Issued By,
and Expired On fields.
