So have have two domain addresses pointing to my IP address.

Both have SSL certificated with letsEncrypt installed for post 443 and 80.

How do i add port 12080 and 22080 and other posts?

I have another sever on another computer which runs on a different port.

Any sugguections?

Scant information… but have you considered reverse proxy?

I guess I should read up on that and see what it is about.

I’m just wondering if it’s an easy way for me to use my router to register SSL certificate

And see if it includes all the port forwarding
