I can't tell what you did and what you pasted from some random wiki.
Here's a rough workflow of adding a couple of new networks for wireless and guest on Unifi/pfSense.
I used vlan 100 for the wireless network, and vlan 200 for the guest in this example. The LAN is assumed to be native. I used foo0 for the network adapter, which isn't a real thing. Substitute igb0, or your lagg, or whatever. I didn't go into details on configuring the interfaces, rules and such. I'm assuming you know how to do that.
Unifi controller-
settings, networks
create new (type vlan only/third party gateway)
name wireless
vlan id 100
create new
name guest
vlan id 200
settings, wifi
name corpssid, password, etc
network- wireless (old version vlan 100)
name guestssid, password, etc
network- guest (old version vlan 200)
You can leave the switchports the APs are in set to 'All'
The port connecting to pfSense should be set to 'All'
pfSense-
interfaces, assignments, vlans, add
select parent interface (usually LAN)
vlan tag 100
description wireless
save
add
select parent interface (usually LAN)
vlan tag 200
description guest
save
back to interface assignments-
Available network ports: vlan 100 on foo0 (wireless) [add]
do the same for vlan 200 (guest)
Now, interfaces, OPTx (foo0.100)
configure interface with unique subnet, etc
Now, interfaces, OPTy (foo0.200)
configure interface with unique subnet, etc
services, dhcp, enable and configure on OPTx and OPTy
firewall, rules, configure rules for the two new interfaces
firewall, nat, outbound. If you're not using automatic outbound nat, add rules for the new subnets
