Is there a way to get Let's Encrypt to work with some other ports beside 80 & 443?

[saskwatch]

I love having subdomains pointing back to my unraid server, as that traffic is being managed by the Let's Encrypt reverse proxy, etc. The problem that I have is that script kids will see that ports 80 and 443 are open on my router. Now all the the horrors of the internet gets thrown at my router.  My logs show all the attempted hacks and port scans.  Then, all of sudden, the internet connection seems to get severed from my router.  When I look at my modem, it is good, but my router is trying to do what it is does when it is getting DDOS'd.

 

QUESTION: Is there a way to get Let's Encrypt to work with some other ports beside 80 & 443, or should I go back to old school port forwarding?
