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.

    ip 10.0.0.1.1/8

    This one was created by AI, right? 😉

    I can not get my host node (the one that is 10.0.0.1/8 in vmbr1) to communicate with that NFS share.

    Go through the usual debugging steps like:

    Can they ping each other? Is the NFS access restricted to certain hosts? Is your NFS mount command correct? Is the service really running when you try the mount?

      It wasn’t created by AI, I’m just a newbie to networking and was pretty tired, at this point I spent ~4 hours on this problem 😅.

      I tried everything, the VMs can ping each other but not the nodes, and the VM can mount and see the NFS share 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, thanks for your time ^^

      Edit: Typo
