I have installed pfsense and It has worked for few days without giving any errors. Suddenly on yesterday, I got an error saying "cannot resolve host name". But when i plug my pfsense into my home router, it doesn't give any errors. Which means i can ping www.google.com and 188.8.131.52.
My pfsense got squid and squid guard. in the general tab I have installed the DNS as 184.108.40.206 and the host name pfsesnse. I have also restated the dns forwarder service. I have enabled the DNS forwarder too. I dont have any firewall rules for this pfsense box.
