iocage jail in FN 11.1 - networking not working

[Kevin Horton]

I'm trying to set up an iocage jail on FreeNAS-11.1, and I can't get networking to work. I can't find many people complaining about similar issues, so I must have mucked up something very simple. I've read what minimal docs I can find. I've restarted the jail, and the whole FreeNAS host, but that didn't help. Any advice is greatly appreciated.

Experimenting a bit more, I can get networking going if I don't use VNET. I selected igb0 as the interface, and deselected VNET, and now I can ping in and out of the jail. Now to see if I can get plex happy in there, so I can start shutting down the warden jails.

I have run into the same thing. I was only able to get networking to work in a new iocage jail by not using VNET and specifying the bridge0 interface on my machine. Haven't gotten as far as getting plex to work yet though.

There is at least one walkthrough on the forums though detailing how to get plex up and running in in 11.1 iocage. Might reference that if you're stuck.

I got two iocage jails up and working (one for plex and one for a bunch of video transcoding tools), so those warden jails have been stopped. Owncloud is next up.

Hi guys I am a noob. I am having the same issue. Any new iocage jail I create doesn't have any internet access. Would you be able to explain how you fixed this. Thank you

In the CLI (or by making the equivalent selections in the GUI):

Code:

iocage stop <JAIL NAME>
iocage set vnet=off <JAIL NAME>
iocage set ip4_addr=<INTERFACE>|<IP ADDRESS>/24 <JAIL NAME>
iocage start <JAIL NAME>

In my case, the following works, but you may need different values for <INTERFACE>, <IP ADDRESS> and <JAIL NAME>

Code:

iocage stop plex2
iocage set vnet=off plex2
iocage set ip4_addr=igb0|192.168.0.221/24 plex2
iocage start plex2

Thank you. It work out
