Openwrt如何设置活动连接上限

要在OpenWrt中设置活动连接上限,可以通过调整conntrack参数来实现。以下是具体步骤:

  1. 修改conntrack最大连接数

    • 通过SSH登录到OpenWrt路由器。
    • 编辑/etc/sysctl.conf文件,添加或修改以下行:
      net.netfilter.nf_conntrack_max=65535
    • 这将conntrack的最大连接数设置为65535。根据实际需求,可以调整这个值。
  2. 应用配置

    • 执行以下命令以应用新的sysctl配置:
      sysctl -p
  3. 使用iptables限制连接数

    • 可以使用iptables来限制特定端口或IP的连接数。例如,限制某个IP的最大连接数为5:
      iptables -A INPUT -p tcp --dport 22 -s 192.168.1.100 -m connlimit --connlimit-above 5 -j REJECT
    • 这条规则限制IP地址192.168.1.100在端口22上的最大连接数为5。
  4. 检查当前连接数

    • 使用以下命令查看当前的连接数:
      cat /proc/sys/net/netfilter/nf_conntrack_count
  5. 注意事项

    • 调整连接数上限时,请确保路由器的硬件资源(如内存和CPU)能够支持更高的连接数。
    • 不同的网络环境和使用场景可能需要不同的配置,请根据实际情况进行调整。

通过以上步骤,您可以在OpenWrt中设置活动连接的上限,以优化网络性能和稳定性。
