I'm not sure about the syntax here: what comes first in /etc/network/interfaces interface names, VLAN or alias? What I want is to setup two different subnets on the same VLAN (temporarily).



It will look something like below, where there's a 10.20.100.100/24 and 10.20.200.200/24 on the same VLAN (id 33):



iface eth0:1.33 inet static

  address 10.20.100.100

  netmask 255.255.255.0



iface eth0:2.33 inet static

  address 10.20.200.200

  netmask 255.255.255.0


I expected the Debian Wiki to answer this but it did not: https://wiki.debian.org/NetworkConfiguration#Multiple_IP_addresses_on_One_Interface

I don't know when and what changed, but you can now define virtual interfaces on vlans:



auto eth0.10

iface eth0.10 inet static

    address 192.168.1.61

    netmask 255.255.255.0

    gateway 192.168.1.11



auto eth0.10:1

iface eth0.10:1 inet static

    address 10.20.100.100

    netmask 255.255.255.0



auto eth0.10:2

iface eth0.10:2 inet static

    address 10.20.100.200

    netmask 255.255.255.0


Think of vlan interfaces as physical interfaces. You add virtual interfaces to the "physical" interface.
