TrueNAS Scale can't connect to VM

[rmvanderspek]

I have a TrueNAS-SCALE-22.02.0.1 running with a VM Ubuntu Server.

I can't ping my VM from the TrueNAS shell.

Code:

root@truenas[~]# ping 192.168.1.26
PING 192.168.1.26 (192.168.1.26) 56(84) bytes of data.
From 192.168.1.253 icmp_seq=1 Destination Host Unreachable

But from my windows PC I am able to reach the VM.

I know that I need to setup a bridge network to be able to reach TrueNAS from the VM, but do I have to do the same to reach VM from TrueNAS? Or is there some other configuration I have not yet thought of that is needed?

do I have to do the same to reach VM from TrueNAS?

Yes, since reachability works in both directions at once... packets need a way to go and to come back for a conversation to work.

is there some other configuration I have not yet thought of that is needed?

Shouldn't be.

Thanks, I will try that.

Well no, not really. This says: Accessing NAS from a VM, but I want it the other way around: Accessing a VM from NAS. (So maybe the documentation title could be changed to: "Establishing communication between NAS and a VM." Which suggests it is a two-way street.)
If what @sretalla is saying is correct, it will work both ways. I will try it tonight. I believe I need to attach a monitor and keyboard to the NAS to create the Bridge, so that's not something I can do between jobs .

you can create the bridge in the gui, no need for monitor and keyboard.

I followed this guide: https://www.truenas.com/docs/scale/virtualization/accessingnasfromvm/, but after 'testing' the new network configuration, the bridge I created had disappeared. After some googling I found this comment: https://www.truenas.com/community/threads/vms-cant-see-host.88517/post-691837 suggesting that it is something I can do in a menu after rebooting.

I can confirm that a combination of the official documentation and the explanation written (here: https://www.truenas.com/community/threads/vms-cant-see-host.88517/post-691837) has solved my issue.

Did you save the Changes? While testing you have 60 Seconds to save the Changes. If you didnt save, the Changes will automatically be reverted

Yes, I believe I did. I recall a counter and pushing some key before it got to zero.

I have exactly the same problem but nothing here helped me to figure out how to exactly set it up so my TrueNAS and VM (Ubuntu server) can see each other.

From my VM I can ping internet and my home router but not my TrueNAS(scale), and from TrueNAS(scale) I can not ping Ubuntu.

I created the br0 interface and assigned it to VM, but it still doesnt work :(
