Internet access blocked just with some devices while pfBlockerNG is active

Hi,

I know there might be something related to my situation in the other threads, but I seem not to find it (at least not equal/similar).

I have a two-instances HA setup (22.01), and I am trying to properly setup bfBlokerNG (pfBlockerNG-devel).

As soon as I set, say, PRI1 rules with Deny Both action and auto FW rules, something in the network goes awful, like my smartphone can't access internet anymore while wi-fi connected to (say) VLAN10, while other devices (on the same VLAN, like the desktop PC I am using, cabled to a Wi-Fi extender - the same I am connected with my smartphone). VLAN10 is among the interfaces I am auto-creating FW rules (they are in the Floating category), outbound, while only WAN is auto-ruled in inbound.

I can share more setups or try to better explain the problem if you need.

Thank you very much,

Hi,

After some troubleshooting, I found out the problem was with Private DNS (dns.google) setting on the phone. Once I set it to auto, everything turned out smooth again.

Thank you.
