Constant network problems in jails

[abrice]

I've been having numerous problems with the networking with the jails (iocage) and I'm at a loss as what else I can do to fix it. It was working in prior releases of Freenas, but the latest version 11.2U7 is causing me major problems. I'm weary of rolling back so I'm hoping someone can help solve this.

All my jails were set to use VNET checked, vnet0 and vnet0:bridge0 with a static IP assigned.

In the jail it has an IP address but I can't ping anything on my local network (see below). I'm really not sure what else I can do and am at my wits end...

Here's my networking info:
