要在Windows Server上設置VPN，需啟用並配置RRAS，設置網(wǎng)絡接口，創(chuàng)建用戶權限，最後從客戶端連接。具體步驟如下：1. 通過服務器管理器添加Remote Access角色並啟用RRAS，選擇自定義配置並啟用VPN訪問；2. 配置網(wǎng)絡接口並正確轉發(fā)PPTP或L2TP/IPsec所需端口；3. 在本地用戶或活動目錄中允許指定賬戶撥入訪問並設置強密碼；4. 客戶端使用Windows內(nèi)置VPN工具輸入服務器地址和憑據(jù)完成連接。

Setting up a VPN on Windows Server is actually pretty straightforward if you know what you're doing. It's not something most home users will need, but for businesses or remote teams, having your own private network can be super useful. The main idea here is to set up Routing and Remote Access (RRAS) — that's the built-in tool Windows Server uses for this kind of thing.

Here's how to do it step by step.

1. Enable and Configure RRAS (Routing and Remote Access)

Before you can start accepting incoming VPN connections, you need to enable the Routing and Remote Access role on your server. This is part of the server's role services.

To get started:

• Open Server Manager .
• Click Add roles and features .
• Go through the wizard until you reach the Server Roles section.
• Check Remote Access , then click Next.
• On the next screen, make sure DirectAccess and VPN (RAS) is selected under Role services.
• Complete the installation.

Once installed, go to Tools > Routing and Remote Access in Server Manager to open the RRAS management console. Right-click your server name and choose Configure and Enable Routing and Remote Access . From there, select Custom configuration , and check VPN access .

2. Set Up the Network Interface for Incoming Connections

After enabling RRAS, the service will ask you to pick a network interface for incoming connections. If your server has multiple NICs, make sure to choose the one connected to the public internet.

You'll also need to decide whether the server should assign IP addresses automatically or use a static pool. Most setups work fine with automatic assignment, but if you have a specific range you want to use, enter it here.

If you're behind a firewall or NAT device (like most home servers), don't forget to forward the right ports:

• PPTP uses port 1723 and GRE protocol
• L2TP/IPsec needs UDP ports 500 and 4500, plus protocol 50 (ESP)

Make sure those are forwarded to your server's local IP address.

3. Create User Accounts or Adjust Permissions

By default, user accounts on the server aren't allowed to connect via VPN. You'll need to give them permission.

Go to Server Manager > Tools > Active Directory Users and Computers (or Local Users if not a domain controller). Find the user account you want to allow, right-click, and select Properties . Under the Dial-in tab, choose Allow access under Network Access Permission.

Also, keep in mind:

• Use strong passwords — these accounts are potential entry points.
• Consider using separate test accounts before giving full access to real users.
• If you're managing many users, group policies might help streamline permissions.

4. Connect from a Client Machine

Once everything's set up, clients can connect using the built-in Windows VPN client.

On the client computer:

• Open Settings > Network & Internet > VPN > Add a VPN connection
• Choose Windows (built-in) as the provider
• Enter the server's public IP or domain name
• Select the type of VPN (PPTP, L2TP/IPsec, etc.)
• Provide login credentials when connecting

A common issue is getting the authentication method right. If you're using L2TP with IPsec, you may need to enter a pre-shared key. Keep an eye on error messages — they often tell you exactly what went wrong.

That's basically it. Once configured, your Windows Server should accept incoming connections and route traffic properly. It's not overly complex, but there are enough moving parts — like firewall rules and user permissions — that it's easy to miss a small detail and wonder why it's not working.
