Dual NIC motherboard, one for FreeNAS, second for jail

[nmnihon]

Hello everyone, I have the following problem while trying to create a jail.

My MBO has 2 NICs. I want one to be used by FreeNAS and the second one to be used by the jail.
I have made a new jail (non VIMAGE one) and designated the second NIC to the jail. Here is the warden output:

Code:

id: 1
host: dns_server
iface: em1
ipv4:
alias-ipv4:
bridge-ipv4:
alias-bridge-ipv4:
defaultrouter-ipv4:
ipv6:
alias-ipv6:
bridge-ipv6:
alias-bridge-ipv6:
defaultrouter-ipv6:
autostart: Enabled
vnet: Disabled
nat: Disabled
mac: 86:e1:bc:aa:e1:80
status: Running
type: standard
flags: allow.raw_sockets=true

However, I am unable to set up the network in the jail. In the jail I am using this in the /etc/rc.conf

Code:

.....
ifconfig_em1="inet 192.168.2.83 netmask 255.255.255.0"                         
defaultrouter="192.168.2.1"

It doesn't work.

Code:

root@dns_server:/ # ifconfig                                               
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500     
        options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>         
        ether 08:00:27:7f:3d:ae                                               
        media: Ethernet autoselect (1000baseT <full-duplex>)                   
        status: active

        options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>         
        ether 08:00:27:ee:9e:40                                               
        media: Ethernet autoselect (1000baseT <full-duplex>)                   
        status: active

        options=600003<RXCSUM,TXCSUM,RXCSUM_IPV6,TXCSUM_IPV6> 

when I try to ping eg. 8.8.8.8 from the jail I get

Code:

ping: socket: Protocol not supported 

Here is the ifconfig output on the host side

Code:

[root@freenas ~]# ifconfig

        options=600003<RXCSUM,TXCSUM,RXCSUM_IPV6,TXCSUM_IPV6>                  
        inet6 ::1 prefixlen 128

        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>  

I've removed IP address settings for the em1 in the console setup.

Any tips how to make it work? I've been searching in this forum and other places but without any luck.

Were you able to figure this out?
