We're migrating from a PA-2020 to PA-3020.
Config migration went fine. And most functionality is ok on the new device.
However our IP helpers don't work anymore. We use them on tagged subinterfaces.
All subinterfaces on one interface connected to switch.
Capture shows the device receives the DHCP discoveries. But it does nothing with them: no drop, no forwarding.
Any ideas what may be causing this ?
