How to safely open ports on server?

Hey guys so I need a service that is having issues connecting. I use cloudflare but for DNS mostly (cloud turned off for everything) and have whitelisted the domains and ip addresses they needed. The service states they need access to

"ports 10,000 - 60,000 UDP/SRTP/SRTCP"

How would I ensure this goes thru for ufw on Debian 9 Apache setup?

I just want to make sure I don't expose too much or do something incorrect. Thanks.
