You can use DNS challenge to renew your certificates without opening ports! Have a look at acme.sh for automation.
Oh, awesome! I thought that was a manual process, so I've been using the regular method.
Looks like I have a new project for this weekend. My DNS is currently hosted at Cloudflare, so this should be pretty straightforward.

certbot has modules for most DNS providers as well.
