Hi,

i still can=E2=80=99t get it to work.

My rc.conf looks like this:

defaultrouter=3D"10.0.3.1"

ifconfig_igb0=3D"inet 10.0.3.11/24 -rxcsum -rxcsum6 -txcsum -txcsum6 =
-lro -tso -vlanhwtso"

ifconfig_igb1=3D"up -rxcsum -rxcsum6 -txcsum -txcsum6 -lro -tso =
-vlanhwtso"
cloned_interfaces=3D"vlan30 vlan40 vlan50 vlan60"

ifconfig_vlan30=3D"inet 10.0.3.12/24 vlan 30 vlandev igb1 description =
LAN"
ifconfig_vlan40=3D"inet 10.0.4.12/24 vlan 40 vlandev igb1 description =

ifconfig_vlan50=3D"inet 10.0.5.12/24 vlan 50 vlandev igb1 description =

ifconfig_vlan60=3D"inet 10.0.6.12/24 vlan 60 vlandev igb1 description =
VOIP=E2=80=9C

ifconfig says:

When I try to bring up a jail on a freshly installed iocage it quits =
with an error.

# iocage create -n "vlantest" -r LATEST defaultrouter=3D"10.0.6.1"  =
vnet=3D"on" allow_raw_sockets=3D"1" boot=3D"on" =
interfaces=3D"vnet0:vlan60" ip4_addr=3D"vnet0|10.0.6.13/24"

vlantest successfully created!
* Starting vlantest
  + Started OK
  + Using devfs_ruleset: 5
  + Configuring VNET FAILED
  ifconfig: BRDGADD vnet0.5: Invalid argument

Stopped vlantest due to VNET failure

What am I doning wrong?=20

Best regards,
Chris
