Can you create a new test jail, and see if DNS works under the test jail?

To add on to this, one of my jails, as you may have seen, is Homebridge, and was installed via the Plugins page. If I try to install any plugin, it tries to connect it to pkg and fails to, which is the same reason why it can't ping domains. I doubt it is a configuration issue.

So, now you're back from U5 to U3 and it still doesn't work? Then it sounds like it probably wasn't the upgrade and something else that caused it that may have been catalyzed by the reboot.

I don’t know. But the screen now just shows this

There is definitely something screw up in that machine or in that network.

Can you take a screenshot of your system's network interfaces?

Your bridge interface doesn't have an IP.

I saw no change with or without one. Is the bridge its own device, or does it share an IP with the jail? I have had 2 jails running on 1 bridge and it worked fine.

In TN you can assign jails and VMs to a network interface, be it a bridge or a phisical one.
@Patrick M. Hausen has already told you the proper way it should be configured.

I don't have a "bridge0" interface in the TrueNAS Core GUI. It only exists when checking with "ifconfig" in the command-line.

Did you manually create the "bridge0" interface using the GUI?

In my case, the bridge is configured per each jail.

For example, a jail will use re0 as the vnet_default_interface, and then under Network Properties the interfaces is vnet0:bridge0

In summary:
  • Before creating any jails, the TrueNAS Core GUI shows the physical network cards that you can configure for the server itself
  • No need to manually create a bridge interface (i.e, "bridge0") in the GUI
  • When you create and configure a jail to use VNET, and assign it a vnet_default_interface (i.e, "re0"), it should automatically create a bridge interface (which will still not show up in the GUI; only in the command-line)
  • You can then confirm this by checking the jail's Network Properties and even using "ifconfig" to check in an SSH session


EDIT:

This might mean you'd have to stop all your jails, then delete "bridge0" via the GUI -> Network -> Interfaces

Then while your jails are still down, configure them to use "re0" as the vnet_default_interface and to use vnet0:bridge0 in its Network Properties for "interfaces"

Then start your jails to finish the process.

13-u5.3 definitely breaks jail networking.
After upgrade from 5.2 to 5.3 all jails networking stopped working, revert to 5.2 fixes it without any config changes.
in 5.3 newly created jails don't work, not in NAT not VNET,
DHCP fails to acquire address
Manual IP assignment results with no connection at all, can't ping host, can't ping other jails, just a black hole.
All my jails are and always were configured as per winnielinne last post.
only change in networking from fresh install is "gateway_enable" tunable and fixed IP for main network interface
ifconfig in jail both 5.3 and 5.2 show the same:

Code:
ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
    options=680003<RXCSUM,TXCSUM,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6>

    inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1

igb0 is missing from the bridge interface. And your configuration is invalid even with U5.2. The IP address must be on the bridge0, not on igb0.

- reboot with all jails autostart disabled
- create an interface of type bridge named bridge0
- add igb0 as the only member interface
- remove the IP address from igb0, instead put "up" into the options field
- put the IP address on bridge0
- test and save - you should increase the timeout from 60 to e.g. 300 seconds before clicking "test", then clear the ARP cache of your desktop system

If that worked, then for each jail:

- vnet_default_interface: none

The rest looks good. Your jails should work afterwards.

P.S. Temporary fix for U5.3: ifconfig bridge0 addm igb0

Permanent fix: see my last post above.

thannk you Sir.
its odd it worked for some 5 years since 11u1 and now stopped...
I'll implement changes later and see if it works in 5.3, its a live production system so can't f-about too much ion business hours.
