    Hello everyone,

    I never added any rules to UFW for NoMachine. Can someone explain to me how NoMachine is working despite UFW being enabled with no specific ports opened on UFW?



    Hello ascwonter,
    NoMachine automatically configures the most common firewalls so users do not have to do it manually. You can find more details about this feature in server.cfg key description.

    # Enable the server to automatically configure the firewall for all
    # the configured services. On platforms that don’t support adding
    # the specific executables to a white list, the needed ports are
    # added at server startup and removed at server shutdown, or when,
    # at run-time, a new port is needed. The default value is 1.
    # 1: Enabled. NoMachine opens the required ports in the firewall.
    # 0: Disabled. Firewall must be configured manually. By default
    # the required ports are TCP ports 4000 for NX, 4080 and 4443
    # for HTTP and UDP ports in the range 4011-4999 range.
    #EnableFirewallConfiguration 1
