对于有外部防火墙的服务器（比如 [EC2](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-security-groups.html)/[GCE](https://cloud.google.com/vpc/docs/firewalls)），请为 VPN 打开 UDP 端口 500 和 4500。

### 无法连接到 VPN 服务器
首先，请确保你的 VPN 客户端设备上指定的 VPN 服务器地址与 IKEv2 辅助脚本输出中的服务器地址**完全一致**。
对于有外部防火墙的服务器（比如 [EC2](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-security-groups.html)/[GCE](https://cloud.google.com/vpc/docs/firewalls)），请为 VPN 打开 UDP 端口 500 和 4500。阿里云用户请参见 [#433](https://github.com/hwdsl2/setup-ipsec-vpn/issues/433)。
### 无法连接多个 IKEv2 客户端
如果要同时连接在同一个 NAT（比如家用路由器）后面的多个 IKEv2 客户端，你需要为每个客户端生成唯一的证书。否则，你可能会遇到稍后连接的客户端影响现有客户端的 VPN 连接，从而导致无法访问 Internet 的问题。

### Cannot connect to the VPN server
First, make sure that the VPN server address specified on your VPN client device **exactly matches** the server address in the output of the IKEv2 helper script.
For servers with an external firewall (e.g. [EC2](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-security-groups.html)/[GCE](https://cloud.google.com/vpc/docs/firewalls)), open UDP ports 500 and 4500 for the VPN. Aliyun users, see [#433](https://github.com/hwdsl2/setup-ipsec-vpn/issues/433).
### Unable to connect multiple IKEv2 clients
To connect multiple IKEv2 clients from behind the same NAT (e.g. home router) at the same time, you will need to generate a unique certificate for each client. Otherwise, you could encounter the issue where a later connected client affects the VPN connection of an existing client, which may lose Internet access.
