    # Sometimes it is desirable to let the sender know when traffic is
    # being denied, rather than simply ignoring it. In these cases, use
    # reject instead of deny. In addition, log rejected connections:
    #- community.general.ufw:
    #    rule: reject
    #    port: auth
    #    log: yes

    # ufw supports connection rate limiting, which is useful for protecting
    # against brute-force login attacks. ufw will deny connections if an IP
    # address has attempted to initiate 6 or more connections in the last
    # 30 seconds. See  http://www.debian-administration.org/articles/187
    # for details. Typical usage is:
    #- community.general.ufw:
    #    rule: limit
    #    port: ssh
    #    proto: tcp  #
    
    # Allow OpenSSH. (Note that as ufw manages its own state, simply removing
    # a rule=allow task can leave those ports exposed. Either use delete=yes
    # or a separate state=reset task)
    #- community.general.ufw:
    #    rule: allow
    #    name: OpenSSH
#
    #- name: Allow all access to tcp port 80
    #  community.general.ufw:
    #    rule: allow
    #    port: '80'
    #    proto: tcp
