I posted this on Reddit before I remembered that this is the better place to come with questions!
I’ve got a question about this new app. Let’s say I wanted to point a domain name at my umbrel:4848. That way I can let friends use my relay without needing to join my Tailscale network. Is there any inherent security risk in making the nostr app publicly accessible?
If it makes a difference 
I’ve got a virtual private server forwarding traffic down a WireGuard tunnel to my home network where nginx proxy manager handles ssl termination and sends the request along to the nostr relay app. No ports are open on my home router.
My thinking is that there’s nothing private on the app page that gets exposed (including the relay address itself) and there aren’t any administrative functions exposed either so it should be safe but I did want to double check that I’m thinking about this right.
