使用iptables配置端口映射方法

1.安装iptables-services

systemctl stop firewalld
systemctl mask firewalld

yum install iptables-services

systemctl enable iptables
systemctl restart iptables

2.配置规则

将 10.129.4.96:5901 端口映射到 10.129.4.90:5911

iptables -t nat -A PREROUTING --dst 10.129.4.90 -p tcp --dport 5911 -j DNAT --to-destination 10.129.4.96:5901
iptables -t nat -A POSTROUTING --dst 10.129.4.96 -p tcp --dport 5901 -j SNAT --to-source 10.129.4.90

3.保存配置

service iptables save
