IPv6 + DNSBL shows some ads still

[mg85]

Hello all,

My ISP provides me with IPv6, which I have configured on the firewall (DHCPv6 on WAN and ‘Track Interface’ on the LAN interfaces I want to use IPv6 on). All works well.

I am using NAT redirect to forward all DNS requests to the firewall.
On the interfaces I have configured pass rules for DNS.
Under NAT settings, I have created two rules:
- one that intercepts all IPv4 traffic and forwards to 127.0.0.1
- one that does the same for IPv6 and forwards to ::1

What I do notice however is that some sites are displaying ads.
In an IPv4-only configuration, the same site is free of ads.

I am suspecting something in my configuration (my hunch is the NAT v6 rule..) is allowing some ads to bypass DNSBL.
Hopefully someone is able to think along in troubleshooting this.

The quick solution was to disable IPv6, although that’s not my ultimate goal
