Pfsense Dns Resolver Error Networking Spiceworks Community I’m new to setting up a pfsense router and am having some odd cases where some url’s are not working. i do have pfblockerng setup, but i’ve tried disabling the firewall removing rules and none of those helped. Working dns resolution is critical for functional access to the internet. before diagnosing dns issues with pfsense® software specifically, start with troubleshooting network connectivity to ensure the firewall has a proper networking configuration and working connectivity.
Pfsense Dns Resolver Error Networking Spiceworks Community Learn how to proceed if pfsense dns resolver is not working. our pfsense support team is here to help you with your questions and concerns. running into dns resolver errors on your pfsense firewall router appliance can be frustrating. especially when it disrupts your network’s connectivity. When on the public internet, dns resolution returns the public ip. when a device is on the private lan, it returns the private ip. occassionally, when accessing the web browser of our pbx, a client may (infrequently) get a message from the pfsense about how this is a potential dns rebinding attack. The dns resolver is reloaded when updating hostnames it learns from dhcp lease data. on busy networks with many dhcp clients, this can result in temporary dns outages as unbound reloads. The dns resolver in pfsense® software utilizes unbound, which is a validating, recursive, caching dns resolver capable of using dnssec, dns over tls, and a wide variety of options.

I noticed that when i make changes related to pfblocker, snort or even dynamic dns, the unbound process sometimes crashes. however, as long as i don’t touch anything, it stays up. These topics cover using pfsense® software to handle dns requests from local clients as either a caching dns resolver or forwarder. when acting as a resolver or forwarder, pfsense software will perform dns resolution directly or hand off queries to an upstream dns forwarding server. Dns resolver is the recommended solution and is enabled by default in current pfsense versions. dns forwarder should only be used in specific scenarios where simultaneous querying of multiple dns servers is required. An administrator may need to troubleshoot issues with certain queries to the dns resolver (unbound) or dns forwarder (dnsmasq). in such cases it can be helpful to view the queries received by the firewall and to see the responses generated.
