openstack 命令行管理十一 - 安全組管理 (備忘)
參考官方資料
You must modify the rules for the default security group because users cannot access instances that use the default group from any IP address outside the cloud. You can modify the rules in a security group to allow access to instances through different ports and protocols. For example, you can modify rules to allow access to instances through SSH, to ping them, or to allow UDP traffic – for example, for a DNS server running on an instance. You specify the following parameters for rules: Source of traffic. Enable traffic to instances from either IP addresses inside the cloud from other group members or from all IP addresses. Protocol. Choose TCP for SSH, ICMP for pings, or UDP. Destination port on virtual machine. Defines a port range. To open a single port only, enter the same value twice. ICMP does not support ports: Enter values to define the codes and types of ICMP traffic to be allowed. Rules are automatically enforced as soon as you create or modify them.
注: 已通過測試, 修改默認 secgroup 或自定義 secgroup 都可以完成數據訪問測試
