    As you may know there are currently two ways of performing a time sync between the local computer and remote time servers:

    1.) over UDP port 123 (SNTP) =to prefer
    2.) over TCP port 37 (TIME) =old

    How do I setup rules in LnS for allowing these timesyncs (especially the first one)?

    Here's your answer.
    I have never seen time-sync on port 37. Must be very old method.

    You can set a rule:
    Allow
    Ethernet type: UDP
    Source Port: 123
    Destination Port: 123

    It is ok:) .

    Allow
    IP
    UDP
    Inbounds & Outbounds
    Destination
    TCP/UDP :port
    Equals
    123 ntp

    It works, but I don't know wherther it is strict enough.
