Hi I have TrueNAS Core running on an esxi VM. Within that I have a Jail that used to be able to fetch package pkg upgrade but no long can after some disaster recovery (I think some network settings were reset during my clumsy handling of this). Any help debugging this would be great, I get the same…

[image] BlownCapacitor: 192.168.50.212 is the Truenas IP and it is working correctly. I also cannot see the bridge in the network devices in the UI for TrueNas Please do this on the host: deactivate autostart at boot time for all your jails reboot your TrueNAS manually create bridge0 with v…

which version of core are you running? Jails on core 13.0 are eol and cant be updated anymore. You’d have to update your jail to 13.4 or 13.5 and that’s only possible if you update your truenas to the community release of 13.3. That update is not available through the truenas webui, you’d have to do…

We won’t even be able to update our jails or packages after April 2026.

come to the dark (scale) side, we have cookies (and docker)

@BlownCapacitor first of all the IP address 192.168.50.212 must be on the bridge interface bridge0, not on the member interface vmx0.

I’m on TrueNAS-13.0-U6.8 I’m not sure how to update the Jail while its in this state, it fails via the UI. My test jail has the same issue and is on 13.5

Checking if this is correct, the Jail’s IP is supposed to be 192.168.50.213 192.168.50.212 is the Truenas IP and it is working correctly. I also cannot see the bridge in the network devices in the UI for TrueNas

Thanks for the detailed steps, I have followed them but have the same issue. Happy to accept advice on what the right way is, unfortunately I would be unable to entirely follow an explanation so don’t worry about that! Jail ifconfig root@plex:~ # ifconfig lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTIC…

Looks good so far. Did the IPv6 DAD related error messages go away, now? Then to your core problem - can you ping the default gateway from the jail and at the same time run on the host e.g. tcpdump -n -i bridge0 host 192.168.50.213 and post the output?

The IPv6 DAD error persists. Jail ping to default gateway yields ping: sendto: Host is down Host tcpdump root@freenas[~]# tcpdump -n -i bridge0 host 192.168.50.213 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on bridge0, link-type EN10MB (Ethernet), capture…

I might do that, but only after I upgrade from my rock solid 32GB of RAM to 128GB.
