You can use a managed switch to get this working if you have a router with too few ports. I have several gl.inet routers running openwrt but they all have 2/3 ports total. I put a TL-SG108E in front of them and use that to tag ports. This particular switch has an interface that is quite easy to reverse engineer, so I have written a script that allows me to easily move ports between VLANs without bothering with the unintuitive web UI.
