Then you can filter the whitelist with nxFilter. Entre em System > Advanced e na aba Admin Access altere o campo TCP Port para 8080, ou outra porta disponível desde que seja diferente de 80 Clique no botão Save. Then I made the primary DNS Server on pfSense to be 10.127.1.240(which is my nxFilter) and the secondary DNS Server 1.1.1.1 and on NxFilter I have made my upstream DNS Server 10.127.1.254 which points back to pfSense. IPv4 TCP/UDP * * * 53 (DNS) * Block All other DNS Servers Have also used the tracert DC1 from another sitess Domain Controller and it works fine. Policy queries over HTTPS will use TCP/443 at default but if you need to use another port you can change it here. When you have a port collision on UDP/53, use this parameter to listen on a specific IP address. Protocol Source Port Destination Port Gateway Description UDP port 53 (domain service): LISTENING or FILTERING. You can run NxRelay with NxFilter for filteirng multiple branch offices or Active Directory integration over cloud. If i change the DNS address on device level to the IP of any other DNS Server it auto-bypass the NxFilter which I understand it will do, thus have I implemented firewall rules to block access to any other dns server, firewall rules as follow. So I run pfSense (10.127.1.254) as the main firewall/router and on a separate device I have NxFilter (10.127.1.240) to filter the DNS content which works great. I want to filter web content at the DNS level.
