      To enhance the KEC instance security, each firewall does not contain any rule in initial state, and all ports are closed. You need to create rules to open corresponding ports. For example, to enable ping, you must add ICMP rules in the firewall.
      The following table lists common rules.

      Service Protocol Port Source IP address
      FTP TCP 21 0.0.0.0/0
      HTTP TCP 80 0.0.0.0/0
      HTTPS TCP 443 0.0.0.0/0
      Ping ICMP N/A 0.0.0.0/0
      PPTP TCP 1723 0.0.0.0/0
      RDP TCP 3389 0.0.0.0/0
      SSH TCP 22 0.0.0.0/0
