Is your feature request related to a problem? Please describe.
It would be nice to have some way of simulating tagged vlans

Describe the solution you'd like
Ideally there should be some sort of switch that has support for vlan tagging. I should then be able to set the vlan tag to match with the router to separate out traffic.

Describe alternatives you've considered
I could use physical hardware

Additional context
Here is the somewhat unrelated OpenWRT vlan wiki page. https://openwrt.org/docs/guide-user/network/vlan/switch_configuration
