Hello, It has been a year since my initial post and I have upgraded PF multiple times and currently using th elatest 13.0.0 but the same DHCP issue remains. I'm forced to run a separate server for DHCP on the registration network as a workaround. Giacinto has confirmed the same issue last time. How do we get this bug onto developers' radar?
