  firewall-cmd --reload
  firewall-cmd --zone=public --list-ports
15.配置fail2ban
  vim /etc/fail2ban/jail.d/freeswitch.local
  [freeswitch]
  enabled = true
  # Ignore failures from our local internal network
  ignoreip = 127.0.0.0/8
  maxretry = 4 ; for a total of five failures
  findtime = 3600 ; based on empirical testing
  bantime = 1200 ; ban for 20m (which lets us pick up repeat offenders)
  # We do not use 5061 and it is not open to the outside world, so act on 5060 only
  port = 5060
  # we do not want mail, so remove that action from f freeswitch config
  action = %(banaction)s[name=%(__name__)s-tcp, port="%(port)s", protocol="tcp", chain="%(chain)s", actname=%(banaction)s-tcp]
      %(banaction)s[name=%(__name__)s-udp, port="%(port)s", protocol="udp", chain="%(chain)s", actname=%(banaction)s-udp]
  # Add intrusion log, which contains special string for host (see freeswitch.local filter)
