Enable IP Forwarding:
sysctl net.ipv4.ip_forward=1 等同于 编辑/etc/sysctl.conf文件,将net.ipv4.ip_forward=1前面的#注释去掉,保存文件,然后执行sudo sysctl -p使其生效
Add your forwarding rule (use n.n.n.n:port):
iptables -t nat -A PREROUTING -p tcp -d 10.0.0.132 --dport 29418 -j DNAT --to-destination 10.0.0.133:29418
Ask IPtables to Masquerade:
iptables -t nat -A POSTROUTING -j MASQUERADE
And that's it! It worked for me in any case :)
