PSB blocking SMB connection in Finder

I recently noticed that the PSB firewall blocks connections through SMB. How do I allow SMB connections in Finder? This happens in macOS 10.15.7 and 11.1. PSB version is 17.10.

    You may enable the following Firewall Rules under Profiles in F-Secure PSB portal. Enter the required information (e.g. Local IP address, Remote IP address, port numbers) for each of the rules.

    Allow SMB over TCP inbound from file servers (Allow In)

    Allow SMB over UDP inbound from file servers (Allow In).

    Hi @MonikaL,

    From what I can see, those kind of rules doesn't seem to be possible for Mac profiles.

    And I just noticed that there was an update for the Mac client published yesterday that supposedly solves this problem.

    Do you know if windows profile kind of firewall rules are in the workings in PSB for mac?
