Hi Mayur, This is what im getting back from the firewall team:- When an FQDN object is committed to the system, the management plane sends out periodic DNS queries to populate this object with IP addresses mapped from the DNS reply. These mapped IP addresses are then be pushed down to the dataplane, where they're used inside the object in the security policy. On the dataplane, this object includes only the IP addresses it receives from the management plane, but no domain information. Each FQDN object on the dataplane is limited to a maximum of 10 IP addresses. No actual URL lookups are performed, which is why a wildcard cannot be used.

Hello all, We have setup a Hybrid Connection Wizard between our on-prem Exchange server and Office 365, Microsoft has provided the following link for reference in regards to firewall considerations (https://bit.ly/3dpfiZs) under SMTP port 25 - the documents lists *.mail.protection.outlook.com as a required under ID#10. Can anyone advise on the easiest method to allow this as a dynamic address to add to our firewall rule for port 25 traffic? I found this article ( https://bit.ly/2L5CtM1) but it seems to be applied to URL whitelisting etc. Would be great if PA or other member can share this element of the Hybrid Configuration Wizard and how they overcame this issue.
