Since I installed ProxMox on my HP Microserver I’ve been meaning to build an isolated lab network rather than having vulnerable VMs in my main environment. My Microserver has two physical interfaces so my plan was to split one of the ports on my router off onto its own VLAN and bind my lab VMs to that.

VLAN configuration in OpenWRT isn’t quite as straightforward as I’d hoped so being able to use the web-based interface to do this would be nice.

Sadly, the “Switch” configuration wasn’t available by default but after a bit of searching I found this OpenWRT forum thread with the answer!

By adding the following snippet to /etc/config/network and rebooting the router, the Switch config tab will be available in Luci:

config switch
        option name 'switch0'
        option reset '1'
        option enable_vlan '1'

config switch_vlan
        option device 'switch0'
        option vlan '1'
        option ports '0 1 2 3 6'

config switch_vlan
        option device 'switch0'
        option vlan '2'
        option ports '4 5'
