How do I redirect a port?
Set Up Port Forwarding

- Type the static IP address you chose.
- Enable the port forwarding rule with an Enable or On option.
Do you send redirects to port 80 or 443?
They should also send redirects for all port 80 requests, and possibly an HSTS header (on port 443 requests). Allowing port 80 doesn’t introduce a larger attack surface on your server, because requests on port 80 are generally served by the same software that runs on port 443.
Can a web server use the port 80?
Since the web server itself is running as a service under a dedicated user that is not root, it is not able to use port 80 directly.
How to redirect port 80 to port 8080?
The first INPUT rule will match traffic arriving at port 8080 which was DNATed (here from initially arriving at port 80), while the second will drop what’s remaining arriving at port 8080: direct connection attempts. Note: if you’re wondering why the state match and the conntrack match look similar, that state has been superseded by conntrack.
What does it mean to redirect HTTP traffic to https?
One of the most common tasks you’ll likely perform is redirecting the HTTP traffic to the secured (HTTPS) version of your website. Unlike HTTP, where requests and responses are sent and returned in plaintext, HTTPS uses TLS/SSL to encrypt the communication between the client and the server.
