Hi there!
I'm seeing some weird issues that I haven't been able to figure out if they're proxmox, networking, or tailscale issues and could use some troubleshooting advice.
On my own network I have a OPnsense router with tailscale on it as an exit node and subnet router (192.168.3.1). I also have a proxmox server (192.168.3.2) that I have on my LAN. The promox server does not have tailscale installed on it. I also have a local proxmox backup server on the network (192.168.3.5).
My goal is to have a remote proxmox backup server located at my parents house, so I have a spare laptop running proxmox (without tailscale installed directly on it), and then I have a virtual proxmox backup server VM (192.168.1.5) installed on it that DOES have tailscale installed on it so I can hopefully use that as a remote PBS instance. When I install Tailscale on the proxmox backup server, the machine does show as online and connected via the tailscale admin console, but I cannot access the PBS web interface at its local IP address (https://192.168.1.5:8007) when tailscale is up, I can when it's down. I can however access it remotely via the tailnet IP:8007 when tailscale is up. I also cannot add the remote PBS via the tailnet IP on my local proxmox server (192.168.3.2) either like I would hope.
Any troubleshooting steps would be appreciated!
