设置端口转发

## 将443端口的数据转发到8006端口
iptables -t nat -A PREROUTING -p tcp --dport 443 -j REDIRECT --to-ports 8006
##可选————禁止访问8006端口
iptables -A INPUT -i ! lo -p tcp --dport 8006 -j DROP
##保存配置
iptables-save > /etc/iptables.up.rules
echo -e '#!/bin/sh\n/sbin/iptables-restore < /etc/iptables.up.rules' > /etc/network/if-pre-up.d/iptables
chmod +x /etc/network/if-pre-up.d/iptables
