VPN客户端是用于在用户和VPN服务器之间建立安全连接的终端设备或软件。
什么是 VPN？
VPN（虚拟专用网络）利用隧道技术帮助您远程、安全且私密地访问互联网资源。当您使用互联网时，VPN 会加密您的个人信息并向公众隐藏您的 IP 地址。对于 VPN 用户来说，这就像计算机直接相互连接一样。
常见网络拓扑：
这里我们以WR2100作为演示。
步骤 1：打开网络浏览器并转到http://cudy.net或http://192.168.10.1 。
详细信息请参阅如何登录Cudy路由器的Web界面？
第 2 步：点击常规设置-> VPN并启用VPN 。
默认规则：允许所有设备或禁止所有设备使用 VPN。
要指定设备，请单击系统状态->设备-> VPN来启用或禁用它。
站点到站点：允许两个站点中的设备相互通信。
VPN 政策：
禁用：无需其他设置。
VPN 终止开关：当 VPN 连接丢失时关闭互联网连接。
域：指定哪些域通过 VPN，哪些不通过
远程子网：指定哪些子网通过 VPN，哪些不通过
步骤3：在协议列表中，选择您需要的协议，然后输入您的VPN提供商提供的VPN信息。
• PPTP VPN
输入 VPN 服务器地址（例如，113.92.73.163）以及 VPN 提供商提供的 VPN 用户名和密码。
• L2TP VPN
输入 VPN 服务器地址（例如 113.92.73.163）、VPN 用户名和密码以及 VPN 提供商提供的预共享密钥。
如果您的 VPN 提供商还为您提供了与帐户绑定的隧道 IP，您可以启用使用自定义隧道 IP选项。
• OpenVPN
单击浏览器导入您的 VPN 提供商提供的配置文件。
• WireGuard VPN
单击浏览器导入您的 VPN 提供商提供的配置文件。
接口和对等点将自动从您的 VPN 提供商的CONF 文件同步。
• ZeroTier 从属
输入 ZeroTier Master 提供的ZeroTier 网络 ID和网关。网关可以在 VPN 状态部分找到。

Request for Help: LANCOM to Cudy LT700 VPN Connection Issue
Hello everyone,
I have a LANCOM 1800VAW modem with built-in IPsec IKEv2 VPN. I’ve successfully established a VPN connection from LANCOM to Cudy LT700. From the Cudy LT700 side, I can access the LANCOM public network and reach all devices on its internal network.
However, the issue is that from the LANCOM 1800VAW, I cannot access the Cudy LT700 modem or its local network. Due to software limitations, I’m unable to apply advanced configurations on the Cudy modem anymore.
I would really appreciate any assistance or suggestions to help resolve this issue.
Thank you in advance,
Fernando

Hello, I have two cudy lt400 routers, I need to connect them through zerotier , the máster and slave zero tier router are connected through a 4g chip, I ping the máster zerotier’s IP from another PC from slave router, the ping does not respond. The other way around neither. Please!!
@yilmar londoño,
Dear Customer.
Thank you for contacting Cudy support team.
Please check if the Cellular IP address is a public IP address? As shown nelow. If the public IP address is the same as the IP Address? If not the same, the Cellular IP address is not a public IP address, then you can’t access the router from the internet. You can try to ask the ISP if they can offer you a public IP address.
Hello, I have two cudy lt400 routers, I need to connect them through wireguard, the server router is connected through a 4g chip, when creating the client and the server, the client never connects to the server, I ping the server’s public IP from another network, the ping does not respond, could this be the problem?
