@viragomann so this is working now but I am not entirely sure how . I kind of stumbled on the "fix".
I have a Google nest for home wifi with multiple ap's around the house. This nest router has its own DHCP service on the 192.168.86.0/24 network. Anyway if I put my test device on this network everything works as expected with pfsense. I don't know is it because it is a different network to the wan interface of the pfsense.
