VLAN tagging is how pretty much all devices are going to implement
this. You really don't want to do anything else -- router ports are
more expensive than switch ports. With a managed switch, the VLANs
all happen behind the scenes. Outside devices just think they're
talking to a regular switch.
For these SOHO devices, the internal switch ASIC removes the tags
before emitting frames. Likewise, when a frame is received, the
switch adds the tags for the benefit of the embedded computer.
Although I haven't tested to see what happens if a frame with a tag
already present hits the switch in one of these things. A proper
managed switch will let you configure the behavior for that scenario
(e.g., drop the frame), but these things are more like "managed switch
lite".
