By default, the WildFire WF-500 WildFire appliance will use the management interface IP address when creating the certificate used for the firewalls connecting to it. This can be an issue if a Fully Qualified Domain Name (FQDN) is desired instead of the IP address.
Resolution
To configure the FQDN and regenerate the certificate on a WF-500 WildFire appliance, enter the following commands:
> configure
# set deviceconfig system hostname your-wf-500-hostname
# set deviceconfig system domain example.com
# commit
Once the commit is finished, the certificate will be generated with both the FQDN specified (your-wf-500-hostname.example.com) and the IP address. Thus, a connection to either can be made successfully.
