What's the security situation when opening a jellyfin server up for casting? (feddit.nu)

when reading through the jellyfin with chromecast guide i realized that it would probably be less effort to just let the casting api be public, with the added bonus that i could then cast my library to any device that supports it. but that seems like it would paint a giant target on the server.

what's the recommended way of doing stuff like this? ideally i want to be able to go to someone's house and just play some of my media on their tv.

not that any of this is doable in the near future, since i'm behind cgnat and won't get my colocated bounce server up until spring.

my registrar provides ddns, but how does that help with cgnat when thousands of people potentially have the same address?

oh dang, i thought i saw docs and comments saying ddns would help behind a cgnat too, must be mistaken. it's just for isps who give semi-static ips that change, not full cgnat. after some quick googling it looks like tailscale or other vpn or cloudflare tunnel are your only options.

as i said i'm getting my bouncer server set back up next year after the datacenter it's in has finished renovations, so actually getting a public address is not the biggest issue.
