In the world of AWS and Azure, the list of IPs on the internet will potentially change all the time for various FQDN so you will end up babysitting your iRule. I would not suggest using a virtual forwarder and iRule for this task.

    This is the cause i want use FQDN and not just the IP: for example for windows update i will set the FQDN, after that Big-IP will ask the ip address relating this server. I know that ip address for automatic updates, for example, change every week.

     

    But i need also to create the connection for single and exact IP.

     

    Maybe i could create 2 irule, ip address destination based or FQDN based.
