在网络安全领域,双重防火墙（Dual Firewall）是一种常见的安全配置，旨在通过内核防火墙和应用层防火墙双重保护，确保即使内核被破坏，应用层依然安全，关于VPS125是否支持双闪，我们需要结合具体服务提供商的配置和文档来判断。

VPS125是否有双闪（双重防火墙）

什么是双重防火墙？

双重防火墙是一种安全机制,通过配置内核和应用层的独立防火墙来增强服务器的安全性，内核防火墙（Ingress/ Egress Filter）负责过滤来自外部的流量，而应用层防火墙（如SSSLite）则负责过滤来自应用服务的流量，这种配置能够有效防止常见的安全攻击，如DDoS攻击、恶意软件注入等。

VPS125的配置

根据VPS125的服务提供商文档,VPS125通常会提供双重防火墙的支持，以下是一个典型的配置示例：

  • 内核防火墙（Ingress/ Egress Filter）：

    # 配置内核防火墙，仅允许HTTP和HTTPS流量通过
iptables -t nat -A INPUT -p tcp --dport 80,443 -j ACCEPT
iptables -t nat -A OUTPUT -i tors -j ACCEPT

  • 应用层防火墙（SSSLite）：

    # 配置SSSLite，允许HTTP和HTTPS流量通过
echo "SSSLite on" >> /etc/sslite.conf
echo "SSSLite off" >> /etc/sslite.conf << "SSSLite off"
if [ ! -z "$1" ]; then
  echo -e "Name Server $1\n" >> /etc/sslite.conf
fi
if [ ! -z "$2" ]; then
  echo -e "Name Server $2\n" >> /etc/sslite.conf

iptables -t nat -A OUTPUT -i tors -j ACCEPT

  • 应用层防火墙（SSSLite）：

    # 配置SSSLite，允许HTTP和HTTPS流量通过
echo "SSSLite on" >> /etc/sslite.conf
echo "SSSLite off" >> /etc/sslite.conf << "SSSLite off"
if [ ! -z "$1" ]; then
  echo -e "Name Server $1\n" >> /etc/sslite.conf
fi
if [ ! -z "$2" ]; then
  echo -e "Name Server $2\n" >> /etc/sslite.conf
