Access Jellyfin outside your home network (Proxmox LXC & Tailscale)

[banchev]

Hi there,

I'm struggling to make my Jellyfin to be accessed outside my home network. For the purpose of solving this issue I'm using Tailscale. So here is what I did:

First of all, here is how my homelab looks: https://prnt.sc/DS_Tj0lX2IV7

1) I've installed tailscale on ubuntu_22.04 and I have configured it following this tutorial: https://www.youtube.com/watch?v=QJzjJozAYJo

2) My LXC of tailscale is under 192.168.0.222/24

3) Then I added the following command in my tailscale container: 
tailscale up --advertise-routes=192.168.0.0/24
iptables -t nat -A POSTROUTING -s 192.168.0.222 -o tailscale0 -j MASQUERADE
iptables -A FORWARD -i tailscale0 -o eth0 -d 192.168.0.222 -j ACCEPT

I've tried also with 192.168.0.222/32 but didn't work.
4) When I do tailscale status, I get this:

5) I access Jellyfin under: http://192.168.0.222:8096/
but when I do it with http://{tailscale-ip-here}:8096/ I run into timeout.

Any suggestions what to do? Thanks!
