I'm have a tremendously difficult time setting up something that seems like it should be easy: VLANS with a pfSense gateway and a bunch of Ubiquiti UniFi gear. The frustrating thing is I've set this up before with a pfSense gateway and UniFi APs, but with a bunch of different switches.

Below I will to be as thorough as possible explaining the architecture of my organization’s Network and documenting our setup so someone could possibly see what I may have messed up.

1st, here is a JPEG of a VISO drawing I made showing the Network overview: enter image description here

Important Info: I am able to SSH into the EdgeSwitch 16XG and ping the gateways of the VLANS (10.10.30.1 and 10.10.40.1). But if I try to login to the wireless networks using these VLANs no IP is given via DHCP on the pfSense appliance. Also, if I try to assign a port on any of my switches to only use a specific VLAN and then connect a laptop to that switch via RJ45 I do not get an IP (just APIPA address and ipconfig /release, ipconfig /renew does not help).

Moving on...

Here is all the configuration I have performed:

Interface assignments in pfSense. The Student Wifi will have VLAN 300, and the Guest Wifi will have VLAN 310. They are tied to the lan port (whcih you can physically see in the overview of the network above).

Ok, that is all: Have I misconfigured something? What am I doing wrong? Why can't my devices get an IP address when connecting to the Wifi attributed with these two VLANs?

  • tl/dr ... however, i used to have a similar setup, here are a couple of issues that are not necessarily immediately visible from these pictures: make sure that the APs are on trunk ports, also make sure you have the approriate firewall rules on the interfaces on the pfsense. – rmalchow Aug 20 '19 at 12:44
  • Thanks for that... but, if you did look you would see the firewall rules are clearly shown. I will accept that it isn't immediately obvious that the APs are in fact set on trunk mode via the UniFi PoE switches (this is also shown in the config photos, but hard to understand because of how Ubiquiti setup works on those pieces of equipment). – Jaxian Aug 21 '19 at 7:21

I solved this issue myself. For any having similar issues you should try running the VLANs on a separate physical port -- i.e. separate from your main LAN port. I'm lucky that our gateway/firewall has 6 ports and many are not in use ;)

So, to recap: All the configuration in the above post is correct. All I did was make a new interface on a different physical port (specifically, igb3). This separated my VLANs from my LAN port on igb1. Everything worked as expected after that.
