了解常见的VPN协议 VPN（虚拟专用网络）是一种通过公共网络（如互联网）建立安全连接的技术。它可以用于保护用户的隐私和数据安全。VPN使用不同的协议来建立和管理连接。以下是常见的VPN协议： 1. PPTP（Point-to-Point Tunneling Protocol）：PPTP是一种最早的VPN协议，它使用GRE（通用路由封装）封装数据包，并使用点对点连接建立安全隧道。然而，PPTP不被认为是安全的协议，因为它的加密机制已被破解。 2. L2TP/IPsec（Layer 2 Tunneling Protocol over IPsec）：L2TP/IPsec是一种结合了L2TP和IPsec的VPN协议。L2TP提供隧道的建立和管理，而IPsec提供数据的加密和身份验证。L2TP/IPsec被广泛用于移动设备上，但它可能受到NSA的监控。 3. OpenVPN：OpenVPN是一种开放源代码的VPN协议，它使用SSL/TLS协议来提供安全的连接。OpenVPN可以在多个平台上运行，并且提供了更高的安全性和灵活性。 4. SSTP（Secure Socket Tunneling Protocol）：SSTP是一种基于SSL/TLS的VPN协议，它使用443端口进行通信，这使得它在防火墙后面也能正常工作。SSTP通常用于Windows操作系统。 选择适合您需求的VPN协议很重要，它将影响您的连接速度、安全性和可用性。请确保您选择的协议能够满足您的特定需求。
