Having some issues in Proxmox trying to learn SDNs (lemmy.dbzer0.com)

I am learning how to configure SDNs and I have created a VLAN that has a bridge vmbr1 in my node with ip 10.0.0.1/8, the VMs (10.0.1.2/8 & 10.0.1.3/8) can communicate correctly between them, but I have TrueNAS in one of them with a NFS share in which I store my ISOs and I can not get my host node (the one that is 10.0.0.1/8 in vmbr1) to communicate with that NFS share.

Is there something I have misconfigured or is it that the VMs inside an SDN cannot communicate with the node host?

Edit: The VMs can ping each other but not the nodes, and the VM 1 can mount and see the NFS share (VM 2) but the nodes can't.

The mount is correct because I've configured it before and it worked, and if I change the network device of the VMs to vmbr1 instead of VlanNet (the SDN) it works again.

If you're talking a tagged VLAN, it doesn't work like that.

Is there a way for a node to mount a NFS share that's inside an SDN? It has to be in a cluster (so I can't use a Simple zone) and has to be isolated from the rest of the LAN
