Port Forwarding/Redirecting (lemmy.dbzer0.com)

I'm a beginner in networking things but due to my ISP I can only open a certain range of ports in my router to be accessible from the outside of my network (something like ports 11000-11500).

That means I can't open port 443 to access my reverse proxy from the outside. Is it possible to redirect all traffic that's coming from one of the ports in the range to port 443 of my server?

I haven't found that possibility in my router (Fritzbox 7530) so is there a way to do this on my server (running Fedora Server)?

At the firewall level, port forwarding forwards traffic bound for one port to another machine on your network on an arbitrary port, but the UI built on top of it in your router may not include this.

If it's not an option in your Fritzbox, your options are:

Make the service running on your internal network listen on one of those high-number ports instead.
Introduce another machine on the network that also performs NAT between your router and your machine
Try to access the underlying firewall in your router to tweak the rules manually. Some routers have an admin console accessible via telnet or SSH that may allow this.
Get a new router.

The first and last options on this list are probably the best.
