#Caddy question: I currently have caddy-l4 set up to respond to requests on port 25565, for a #Minecraft server. This works, but because the domain and all subdomains on it use the same A record, you can put any subdomain into the Minecraft client, and it'll work exactly the same. i.e. domain.com, minecraft.domain.com, cats.domain.com, etc. etc.
Is there any way to get caddy-l4 to only respond if the Minecraft client tries to access the port from a *specific* subdomain? I'm thinking this is a dead end--I couldn't coax either the http or tls matchers into working--but I'd love to be wrong!
(I'd also accept an alternative to Caddy that can do this, but it would need to be similarly full-featured and painless to set up/maintain, and I'm not sure that such a thing exists!)
