firewall rules to allow outbound access via FQDN

is it possible to permit outbound ftp access on ISG1000/2000 by just referring to FQDN such as ftp.company.com

 

ftp host address changes and firewalls needs to repsond to different DNS resolutions

Re: firewall rules to allow outbound access via FQDN

How frequently does the IP address of this FTP FQDN changes ?

At any given point of time, does this FQDN resolve to only one IP address or multiple ?
