@onepiece said in Creating VLANs and subnets (and SSIDs) using pfSense:

Do most modern APs allow multiple SSID transmissions using separate subnets simultaneously?

Proper APs usually do, but using a router as an AP won't. Just read the specs to see what an AP can do.

I have a Unifi AC-Lite AP, which supports multiple SSIDs and VLANs, as did a TP-Link AP I used before.

BTW, some people here like the Unifi APs.

As long as the ends have different addresses, within the same subnet, it should work. PfSense does that for you automagically. It assigns the first usable address to itself and subsequent addresses to the client(s). All you have to do is pick the subnet.
