Hi,

We can restrict FRS replication traffic to a specific static port. However, if there is an intermediate network device or software that is being used to filter packets between domain controllers, we need to verify that the device or the software allows communication over the specified port. Additionally, make sure the destination TCP port that we set is open on the firewall.

Regarding restricting FRS replication traffic to a specific static port, the following article can be referred to for more information.
