    You would create 'service-port-range' as a string type data group under Local Traffic -> iRules -> Data Group List. Populate the data group with your port objects.

    reject
    }
}

Thank you so much! I had seen references to the iRule, but had no idea about the data group list. This is working perfectly now!
