Are you using torsocks to run bostr2? I figured if the bouncer is not torified the outgoing websocket connections are leaking the public IP of the server to the connected relays. (The client is safe.) My systemd service here in a #Raspiblitz PR: https://github.com/raspiblitz/raspiblitz/pull/4724/files#diff-0ffb074f869361719e03a7d89046a39b7890b10abe0895f60c0d8a50c3c3b520R136-R160
I discovered tor-router recently and installed it in the #ProxMox #LXC that runs #bostr. https://github.com/Edu4rdSHL/tor-router
Great find, I also had it starred already! Can be suitable for a private server. My home nodes are mostly in hybrid mode using a VPN (Tailscale / Tunnelsats) to some VPS to create clearnet endpoints. Also there are some basic things (like apt updates) I prefer doing over the clear for the speed.
