Hello, I essentially have 2 connections & 2 pfsense firewalls. 1 is connected to our managed switch (Dell poweredge pos) 172.16.9.1/24 and the second one previously died without any configurations saved (durrrp previous IT guy). I got the new one back, setup the vlans to match the gateways of the wireless networks on the unifi controller (this is on a 172.16.9.# internal server), the wireless guest networks are 192.168.2.1/24 & 192.168.3.1/24, I am not understanding how the previous IT guy was able to have both of these Firewalls plugged into the same switch, have DHCP turned on, and yet the wifi devices reaching out to the AP's - unifi - pull IP from 2nd firewall, I am afraid to turn DHCP on and plug it into the switch as this could take down the production network. I have been reading for hours and need a hero.
