I wanted to have 2 VLANs on my router. So I configured it this way:

etc/config/network:

#### VLAN configuration
config switch eth0
        option vlan0    "1 2 3 5*"
        option vlan1    "4 5"
        option vlan2    "0 5"

#### Loopback configuration
config interface loopback
        option ifname   "lo"
        option proto    static
        option ipaddr   127.0.0.1
        option netmask  255.0.0.0


#### LAN configuration
config interface        lan
        option type     bridge
        option ifname   "eth0.0 ath0"
        option proto    static
        option ipaddr   172.16.1.1
        option netmask  255.255.255.0

#### WAN configuration
config interface        wan
        option ifname   "eth0.1"
        option proto    dhcp

#### LAN2 configuratione
config interface        lan
        option ifname   "eth0.2"
        option proto    static
        option ipaddr   172.16.2.1
        option netmask  255.255.255.0

but vlan2 isnt running, while the other vlans work as configurated..

ifconfig:

You should use a different interface name for eth0.2 (not "lan" as it is used for the lan bridge). I use "dmz", and it works.

Hi,

you try to use to IP based VLANs
VLAN1: 172.16.1.x/24
VLAN2: 172.16.2.x/24

Have you ever write the needed iptables rules here ???
And think about this

You should use a different interface name for eth0.2 (not "lan" as it is used for the lan bridge). I use "dmz", and it works.

Because the eth0.2 wasn't listed at "ifconfig -a"
