You can create a transform rule (iirc, might be one of the other rules, can’t check right now) that changes the destination port as long as you’re using Cloudflare’s proxy, no need for stuff like srv records.

edit; alternatively you can use cloudflare’s tunnels feature if forwarding doesn’t work

It doesn’t prove you’re not a bot though, only that the request is coming from a ‘genuine device’. You just need to pipe your malicious requests through a ‘real browser’ to get them approved and you’re set.
