So, hate to break this to you but it's been almost 20 years since you shouldn't just open ports directly to your computer from your home router AND it's been about that long since ISPs just don't allow traffic to customers on standard ports like 80, 443, 21, 22, etc.

The way to do this is actually to have multiple computers, with the first computer acting as your firewall, IDS, and IPS. That computer should run no other services and should be heavily locked down after it's setup, as in most things should be made read-only except the few variable files that are required for operations.

That computer should then route traffic to computers behind it that provide services like https, ssh, etc. This setup makes everything much safer.

But you'll still have to contend with your ISP and they don't usually budge, so you'll have to run services on non-standard ports.
