Access TrueNAS Scale apps via Tailscale - eviltoast

Hey! For a while now I’ve been using Tailscale to access some of my apps in TrueNAS Scale remotely. Since I also want to be able to access my SMB shares on Truenas, I have so far always resorted to setting both Tailscale and the corresponding apps to using host networking.

Not all apps natively support host networking though (e.g. the Immich Community app). Because of this, I cannot access Immich via Tailscale since it is not “listening” on the Tailscale interface/Tailscale IP range.

Is there any option to either configure Tailscale in a way that it can access both TrueNAS apps and host system services like SMB or alternatively some way to make TrueNAS apps listen to requests from the Tailscale interface as well?

Thanks in advance!
