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。

Hello. I can’t resolve the domain. YouTube seems to use DGA domains. Like rr5—-sn-q4fl6n6s.googlevideo.com, rr4—-sn-gvnuxaxjvh-c356.googlevideo.com and (part).googlevideo.com is always different. Is it possible that the router can’t resolve 3rd level domains, etc.? It works in the OpenWRT firmware, but not in yours. What should I do?
I repeat, I can’t get a list of addresses, and I can’t list them in the router config either. Moreover, adding each domain manually also takes a long time.
@danrer,

“I bought a WR3600H, set up a VPN on it, it works, but the problem is that the rules don’t work. Only 3 sites should work through vpn. I did everything according to the instructions. I’ve been communicating with support via email for almost a month now, but their responses are so slow and don’t help solve the problem.”

Dear Customer,
Thank you for contacting Cudy support team.
I think the reason is about the routing rules. You need to set the routing rule on the LANCOM 1800VAW to access the LAN subnet of the LT700. The destination is 192.168.10.0 255.255.255.0 by default, via IPsec interface.
“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

Dear Jose,
Thank you for contacting Cudy support team. I need some more information to fix this issue.
1. What do you want to access via the Zerotier? The WEB page of the master or slave router? Or there is a server in the LAN area of the master or slave router?
2. You can try to follow the instruction on the website to set it.

Most of the time, you need to do two other things:
First, change one of the router’s LAN IP address (default is 192.168.10.1/24) to other subnet, such as 192.168.20.1/24.
Second, set the routing rules on the Zerotier management WEB console.
“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!!”
