    ```
 
    **注：** 为要分配静态 IP 的每个客户端添加一个新的 `conn` 小节。`rightid=` 右边的客户端名称必须添加 `@` 前缀。该客户端名称必须与你在[添加客户端证书](ikev2-howto-zh.md#添加客户端证书)时指定的名称完全一致。分配的静态 IP 必须来自子网 `192.168.43.0/24`，并且必须 **不是** 来自自动分配的 IP 地址池（参见上面的 `rightaddresspool`）。在上面的示例中，你只能分配 `192.168.43.1-192.168.43.99` 范围内的静态 IP。
+
+   **注：** 对于 Windows 7/8/10/11 客户端，你必须对 `rightid=` 使用不同的语法。例如，如果客户端名称为 `client1`，则在上面的示例中设置 `rightid="CN=client1, O=IKEv2 VPN"`。
 1. **（重要）** 重启 IPsec 服务：
    ```
    service ipsec restart

    **Note:** Add a new `conn` section for each client that you want to assign a static IP to. You must add a `@` prefix to the client name for `rightid=`. The client name must exactly match the name you specified when [adding the client certificate](ikev2-howto.md#add-a-client-certificate). The assigned static IP(s) must be from the subnet `192.168.43.0/24`, and must NOT be from the pool of auto-assigned IPs (see `rightaddresspool` above). In the example above, you can only assign static IP(s) from the range `192.168.43.1-192.168.43.99`.

 1. **(Important)** Restart the IPsec service:
    ```
