pfSense would sometimes not resolve

Just as the title says. Sometimes, pfSense won’t resolve names. Ironically, I think, it won’t resolve this forum’s IP. I had to restart the DNS resolver service before I could type this. I’m using pfblockerng and DNS Resolver. Any ideas on what I should tweak?

EDIT: For now, I’ve enabled DNS Query Forwarding and now resolving names. But I would like to get to the bottom of this issue.

My guess is that some list you are using in pfblocker has me blocked.

Hi Tom! I use the default list in pfblocker and didn’t add anything. Also, when I restarted the DNS Resolver service without enabling query forwarding, it got fixed, so maybe it’s not that. But then I encountered another address not resolving so I finally just enabled query forwarding.


Just an update, when I disabled DNSSEC support, it resolved the websites that won’t with it enabled. Could you guys try this page: It’s a National Institutes of Health page for protein structures. I find it weird that there could be a DNSSEC problem with them. Thanks!
