TrueNAS network is ok, but Jail VNET + DHCP fails

[sjean233]

Hi,

I'm really stumped. I'm running TrueNAS-12.0-STABLE (core)

I have a 10 GbE NIC add-in card that is correctly detected by TrueNAS Core. All services, tasks and sharing are ok.

Jails configured with VNET + DHCP + Berkeley Packet Filter report this error when starting.

Error: [EFAULT] + Acquiring DHCP address: FAILED, address received: 0.0.0.0/8 Stopped Jail-Net-Test due to DHCP failure

If I switch the jail to VNET + NAT and forward the ports used by the application, then the jail boots correctly and I can access the application.

How can I get VNET + DHCP to work with my 10 GbE NIC?

Ok I have the same issue on 13 -U2 (ain't sure , the one I downloaded Two days ago). Here is what I have :

This is what I get when I try to start the Jail:

Logs don't tell me much unless I'm not looking at the right place :

I think the answer lies at https://www.truenas.com/community/threads/jails-assigning-separate-nic.82774/ you need to setup a bridge interface as per https://www.truenas.com/docs/core/coretutorials/network/interfaces/bridgecreate/.
Have not tried yet but it's the next thing on my list.

Hey guys, I am not a very technical person with BSD, etc... But I have been trying to install the PlexMediaServer plugin on my own TrueNAS machine (version 13.0-U3) and am getting the same "FAILED, address received: 0.0.0.0/8 Stopped Jail..." error. Has anyone figured anything out one way or another? I followed the threads mentioned but am not sure what a definite answer to this issue was. Is this a problem with DHCP and having a 10g network card/switch? Note: I also have 10g switch and nics between TrueNAS and my workstation. Or do I indeed need to create at least ONE bridge interface first? Again, I am not very well versed w/ networking and BSD internals, so reaching out for some guidance here if possible.

Another question... if I DO have to create a bridge... my current adapter is configured w/ DHCP. If I create a bridge and define my CURRENT physical NIC to be a "member" of the bridge, do I need to enable "DHCP" on the bridge interface itself? Will the current DHCP IP assignments of the physical interface go away? Will I loose connectivity to the TrueNAS machine on my network? I am accessing everything with the Web GUI and want to be sure I do not loose connectivity as I have a lot of important data on this machine. Finally... I notice in your screenshots above, you have the option for "VNET" and "Berkley Packet Filter", I have NEITHER of those available when I am trying to add the plugin. Is the DHCP expected to come from my router? Or does it come from some internal VNET within BSD?

Thanks to all. I look forward to your response. Thanks in advance for your time.
