So this is what i'm trying to do:
I have a physical NIC with dev name eth0 with ip 192.168.1.2 and gateway 192.168.1.1 and I want to setup a VLAN with ip 192.168.1.x and same gateway as eth0.
Setting up the VLAN runs smoothly and i give the VLAN a iface name of eth0.10 and an ip of 192.168.1.69. Now when trying to establish a connection i get an error:
holmen@filserver:~$ sudo ifup eth0.10
Set name-type for VLAN subsystem. Should be visible in /proc/net/vlan/config
RTNETLINK answers: File exists
Failed to bring up eth0.10.
So how do I get the VLAN to connect to the internet and what does the error message mean? My guess s that it have something to do with the broadcast.
Please help!
Settings: /etc/network/interfaces

iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet dhcp

netmask 255.255.255.0

iface eth0.10 inet static

netmask 255.255.255.0
gateway 192.168.1.1
I have removed the auto eth0.10 since i dont want to establish it at startup
