Is anyone using Cloudflare with their BBS/homelab?

I'd like to use it as a WAF in front of the BBS's web server, as I see a lot of crufty traffic hitting my server. The only problem is that I use all of my services off of one hostname - and Cloudflare is only handling 80/443.

It looks like their might be a way to use SRV records to define alternate hosts for different ports - does anyone do that to, say, route binkp/binkps traffic around the WAF to your home server?
