@bryan-paradis This is Funny and I know this is an old topic, but sometime ago I added a 5th Nic to my PFsense, it never worked. Added VMX that did not work either, today I tried again multiple times to no avail and stared over like 3 times. Then I decided to enable track interface and I got ipv6 and it worked I could ping tracert every thing for the first time my 5th Network card was operational, just not on ipv4. I am trying to setup a vlan for wifi in another location in the building. Well I followed your suggestion above even though the path was a little wrong but I fixed the Rule that was not auto created for some reason. Now I have the extra Vlan and the 5th network card working in a virtualized pfsense.
