将外部IP地址路由到内部IP否DNS

Question

我有一个地址69.39.239.211（外部）我想路由/重定向到192.168.0.22（内部）进行一些调试测试。我有一个dd-wrt路由器，所以我可以根据需要更改iptables，我只是不确定语法。我所看到的一切都试图通过DNS来做到这一点，但由于它是一个地址，所以dns从不参与。

到目前为止

iptables -t nat -A PREROUTING -i br0 -d 69.39.239.211 -j DNAT --to 192.168.0.1

将正确跟踪路由但nmap不会看到任何开放端口。

Answer 1

Here's the answer for anyone seeking to do that same thing. What was missing was the second line. I also added the local subnet.

iptables -t nat -A PREROUTING -i br0 -s 192.168.0.0/24 -d 69.39.239.211 -j DNAT --to 192.168.0.1
iptables -t nat -A POSTROUTING -o br0 -j MASQUERADE
