Redirect port 443 (https) to IP using iptables

Question

I've tried for some hours to do this simple job, but it is not so simple like you think.

I wanted to redirect every request for 443 and 80 port to a webserver , in my example http://127.0.0.1:80

Port 80 worked without any problems, but 443 port tried me a lot of time...

I guess you've tried already to run the following command:

iptables -t nat -A OUTPUT -p tcp -m tcp --dport 443 -j DNAT --to-destination 127.0.0.1:80

But this is wrong, because the port 443 cannot be redirected to other ports than 443.

Answer 1

The solution is:

Use the following command:

iptables -t nat -A OUTPUT -p tcp --dport 443 -j DNAT --to-destination 127.0.0.1:443

Then enable https for apache.

Good luck.
