I did try the same ndpi firewall rules on a fresh installation and they work fine.
So i deleted all my firewall rules on the production router, then restarted and made every rule again and now seems to be working again.
Is there a way to export firewall rules to a file in order to restore them o share them amongst other zeroshell routers? the same thing would be awesome fot the dchp static leasings.
Thanks for the support, and this great software!
