Title: Strange navigation problem
Post by: Camilo625 on September 09, 2017, 07:34:03 pm
Hi, i'm having a weird problem on a fresh install of opnsense, after i configure a few things, i loose navigation to some sites, for example, i can load this forum fine, but google.com or youtube.com will timeout and same happens if i try to ping them, would love any help to troubleshoot!

Here is some extra info:
The box it's running opnsense 17.7.1_2, it has two wan ports but only one in use, and multi wan isn't configured(only the grouping), has google DNS set under system/settings/general and "Allow DNS server list to be overridden by DHCP/PPP on WAN" its off, its running behind a router but with dmz on, unbound dns is ON and forwarding mode as well

Maybe a DNSSEC issue?

I have trouble with DNSSEC in my home network because of ISP meddling... Some sites refuse to resolve.


Cheers,

You could also flip Unbound to forward mode or use Dnsmasq.

I have been unable to resolve the issue for this particular line, but another one works flawlessly with the default Unbound settings.

I advise you to try to disable only "Harden DNSSEC data" at first: I had same problems after fresh installs, especially since Unbound became the default resolver in OPNsense; disabling "Harden DNSSEC..." solved everything.

(Services -> Unbound DNS -> Advanced)

Case it's not enough, next step would be to disable DNSSEC completely, if you don't need DNSSEC.
I wouldn't throw-out Unbound DNS for DNSmasq DNS just for DNSSEC issues, Unbound is IMHO far more customizable and versatile.

Good luck!
