Accessing a VM from other containers internally while not allowing containers to access each other

I am going to attempt to run TrueNAS on my proxmox server (I don't have proxmox set up at the moment but i've used it before so i know the basics.)
On this TrueNAS server I would like to access it from two different locations:
Over tailscale, So that I can access shares remotely
Internally, so that other containers on my proxmox server can mount shares

I would like to make it so that every container is able to communicate with the TrueNAS server, but not able to communicate with each other. How might i best accomplish this?
 
Hi,

How about using the built-in Proxmox VE firewall to isolate the containers from each other?

For example, you could allow each container to access the TrueNAS VM on the required ports (such as TCP 445 for SMB), while blocking traffic between the containers.
