I would like to make some of my self-hosted services externally accessible. Currently I use a VPN to access stuff externally, however this doesn’t work on all use-cases. I also use Tailscale for some things.
I would love to use cloudflare tunnels and another auth solution (like keycloak) to replace Tailscale and the VPN.
Is this feasible?
My end goal would be to setup Immich for my family, and have them not have to worry about Tailscale, a VPN or anything other than some initial login to keycloak (for example)
None. Dashy’s authentication was famously literally security theatre even with Keycloak. You could just pause the load in browser and have full access to the config. Because it let you iframe whatever you could now do so with local services to enum. Somehow Jellyfin is unbustable though. So it’s a bit of a crapshoot. Look at past vulnerabilities. Stuff like XSS unless stored you don’t need to worry about, clickjacking, tab nabbing etc. On the other hand anything that’s arbitrary file read, SQLI, RCE, LFI, RFI, SSRF etc. I would look at seriously. E.g. don’t make your 13ft public because it can be used to literally enumerate your entire private network.
