Hi, I need you help guys, my setups is this:

RPi5 with et0 connected to Vodafone Station Router

I use iptables as firewall, my INPUT policy is to drop everything except for ports 53, 80, 443, (ssh port) and vpn port, both tcp and udp for each of them are allowed.

I use pivpn wireguard on port 5****, so my router has a port forwarding on that. The vpn works like a charm.

For networking i use the RPi5 network manager (nmtui), I set up a static ip 192.168.1.8, as default gateway the address of the router and as dns server again the address of the router 192.168.1.1.

I set pihole with google dns but if i set “allow all” on the connection security section I get warnings of too much queries (things like 150 or 1000 queries per minute) if I only permit one hop devices I don’t get any queries but from the localhost of the pi. On my router i set the DNS for all devices to be my RPi5 ip.

Even when I’m getting queries pihole doesn’t work, I added instagram.com on the blocklist but I can access it flawlessly.

Any ideas, please? :/
