Also -- just a thought. You're using epair interfaces. Your jail is using epair0b (you can see this from ifconfig inside the jail). From the host (freenas), your ifconfig bridge0 has members igb1 and vnet0:1, however there is no corresponding epair0a interface.

Take a look at my bridge0 in my setup:
Code:
bridge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    ether 02:f6:c7:64:02:00
    nd6 options=9<PERFORMNUD,IFDISABLED>
    groups: bridge
    id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 15
    maxage 20 holdcnt 6 proto rstp maxaddr 2000 timeout 1200
    root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0
    member: vnet0:4 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
            ifmaxaddr 0 port 13 priority 128 path cost 2000
    member: tap0 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
            ifmaxaddr 0 port 12 priority 128 path cost 2000000
    member: epair2a flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
            ifmaxaddr 0 port 11 priority 128 path cost 2000
    member: epair1a flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
            ifmaxaddr 0 port 10 priority 128 path cost 2000
    member: epair0a flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
            ifmaxaddr 0 port 9 priority 128 path cost 2000
    member: tap1 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
            ifmaxaddr 0 port 8 priority 128 path cost 2000000
    member: vlan1 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
            ifmaxaddr 0 port 6 priority 128 path cost 55


I'm using a vlan setup however my vlan1 is equivalent to your igb1. I also have one jail with vent0:4 and a bunch of epairs.

Huh...how do I add it? If I run the command that I did to add igb1 I get the following error:
Code:
root@Alexandria[~]# ifconfig bridge0 addm epair0a up
ifconfig: BRDGADD epair0a: No such file or directory

I thought iocage was supposed to create the epair interfaces when creating and bringing up the jail(s). Usually the epair(a) is listed in the ifconfig if this command is run on the freenas host or the host that is running the jails -- presumably freenas. How did you create your jails? What version of freenas are you running?

Try rebooting freenas to make sure things aren't screwed up. There is definitely a method of creating and adding epair(a) to the bridge and also adding epair(b) to the vnet bridge -- however I know how to do this from the command line, but not automate it so it happens at every reboot of the machine. I thought part of the iocage executable's job was to create these interfaces by default -- I'm really not too sure.

Link for manual creating of epairs: https://forums.freebsd.org/threads/jails-vnet-freebsd-mastery-multiple-interfaces.70356/

Addendum:
I just read the man page for epair (https://www.freebsd.org/cgi/man.cgi?query=epair&sektion=4&manpath=FreeBSD+8.0-RELEASE) and found this
Each epair interface pair is created at runtime using interface cloning.
This is most easily done with the ifconfig(8) create command or using the
cloned_interfaces variable in rc.conf(5).
So knowing this, you might want to create a system tunable within freenas
System->Tunables-> Variable=cloned_interfaces, Value=bridge0, Type=rc.conf.
After making the system tunable, its probably just easier to reboot the system although you could probably just restart the networking stack tbh. When in doubt just reboot. rc.conf read at startup.

I added the tunable, but no luck. I do have epair0b in the jail, but no epair0a in freenas. I created the jail a few different ways, this time from the GUI but I've also tried from command line as well.

EDIT: running FreeNAS 11.2U7

Just deleted the jail and recreated using the method here: https://www.ixsystems.com/community/resources/fn11-2-iocage-jails-plex-tautulli-sonarr-radarr-lidarr-jackett-transmission-organizr.58/

echo '{"pkgs":["plexmediaserver-plexpass","ca_root_nss"]}' > /tmp/pkg.json
iocage create -n "plex" -p /tmp/pkg.json -r 11.2-RELEASE ip4_addr="vnet0|192.168.0.101/24" defaultrouter="192.168.0.3" vnet="on" allow_raw_sockets="1" boot="on"

Perhaps I'm going down the wrong path. I started a few more jails in the gui and then locked in the system logs (which is black console at bottom of gui) and found something similar to this:
Code:
Jan 16 23:20:19 freenas epair5a: Ethernet address: 02:a8:d0:00:0f:0a
Jan 16 23:20:19 freenas epair5b: Ethernet address: 02:a8:d0:00:10:0b
Jan 16 23:20:19 freenas kernel: epair5a: link state changed to UP
Jan 16 23:20:19 freenas kernel: epair5a: link state changed to UP
Jan 16 23:20:19 freenas kernel: epair5b: link state changed to UP
Jan 16 23:20:19 freenas kernel: epair5b: link state changed to UP
Jan 16 23:20:19 freenas kernel: epair5a: changing name to 'vnet0:7'
Jan 16 23:20:19 freenas kernel: epair5b: changing name to 'epair0b

Discouraging since things would seem to be configured of. Ok -- did you use a plugin to install the plex jail? Have you tried creating another "scratch jail" or test jail from the jail interface?

Make sure you reboot to reset things. Can you post the iocage and ifconfig from the freenas host again?

I moved the server to my home network just in case our corporate firewall was somehow at fault which is why the IPs are different now. Freenas is 192.168.10.5, gateway is 192.168.10.1, and plex is 192.168.10.20, with the test jail setup at 192.168.10.30.

EDIT: for kicks I used the plugin and created a plex server using DHCP and got the following error:
[EFAULT] Exception: RuntimeError: + Acquiring DHCP address: FAILED, address received: 0.0.0.0/8 Stopped plex due to DHCP failure occured, destroyed plex.

Then I created one using a static and got this:
[EFAULT] Exception: CallError:[EFAULT] pkg.cdn.trueos.org could not be reached via DNS, check your network occured, destroyed plex.

Can you ping on jail from another?

Honestly, its very frustrating for sure. I'm sure you've restarted the FreeNAS system a lot -- I find this clears out a lot of crud when I'm making a bunch of networking changes.

What version of FreeNAS are you using? I recently upgraded to 11.3 RC2 last night. I'm not sure that would solve all your problems since honestly it looks like you've configured things appropriately. You wouldn't happen to accessing the box wirelessly over a network or one with restricted policies?

I'm using 11.2U7 - I'm a little hesitant about moving to something labeled "testers only" since this server does house some irreplaceable data. I do have a wireless network but the server is hardwired and I'm accessing it through a hardwired connection as well. And between the two networks I've tried I don't know of any restrictions in place.

Perhaps you could try one of the other networking ports.

Comparing your jail config to one of mine, the only difference is that I have Berkeley Packet Filter disabled, though I am not sure if it would make a difference.

I agree with KevDog to try a different network port. Out of curiosity, what hardware are you using? and are there any reported problems with such hardware and the configuration you are attempting?

Thanks y'all - I'll whip up another ethernet port and see if that makes a difference. I've built this FreeNAS on a Supermicro 2U 12 bay X9DRI-LN4F+ which has 4 LAN ports, so I'll try another one. 6x 2TB SATA drives in RAIDZ2, basic USB stick for boot.

And interestingly I've got another FreeNAS box on my work network, also running 11.2U7 and I was able to create a pingable jail no problem.
