[Elvio_Corte]

Description	This article describes the behavior change when searching for services by port number in the Firewall Policy configuration In FortiOS 7.4.5 onward and 7.6.
Scope	FortiGate.
Solution	In 7.0, 7.2 and 7.4.1 and below: When searching for a service by port number in a firewall policy (for example, '44'), Fortinet will show all services and service groups where '44' is present. For example, HTTPS(443) and SMB(445). It is therefore unnecessary to specify the full service port number. In 7.4.5 onward and 7.6 there is a behavior change: When searching for a service by port number in a firewall policy (for example, '44') there are no results. It is necessary to specify the full service port number to obtain the desired results (this is the behavior change). When typing the full service port number (for example, '443'), it will return the specific service. In this case, HTTPS and all service groups where this service belongs: Note: In FortiOS version 7.4.2, 7.4.3 and 7.4.4, there is a bug (bug_id=1013488) where, when searching by service via port number, there are no results at all. This bug is already fixed in FortiOS 7.4.5.
