Hi, by default built-in relay only work in local network, if you want to expose it to internet, you can run proxy like ngrok or cloudflare tunnel

I still thinking about support proxy by default, but it require a lot of infrastructure, and it increase centralize problem, so I add this plan to backlog

If you know any proxy service which is open source and have free plan, you can suggest it to me, I consider support it for lume 

 Maybe some others in the nostr developer community would be interested in setting up a service to plug into lume. Maybe even pay via bitcoin or something
