cannot resolve any name

norbi771

I already commented https://forum.netgate.com/topic/162839/internal-dns-server-not-working describing my problem, but as issue becomes hot I decided to describe my problem again as separate topic:

my setup is

PFSense Netgate XG-7100 
2.4.4-RELEASE-p3 (amd64)
built on Thu May 16 06:01:19 EDT 2019
FreeBSD 11.2-RELEASE-p10

My PFSense box is unable to resolve any address (I think it may be related to a power outage).
I disabled forwarder and resolver, just to stay on /etc/resolv.conf but my pfsense box is still unable to reach any named address. Computers in LAN (if 8.8.8.8 as dns server is given) can resolve addresses properly.

root: dig google.com +trace

; <<>> DiG 9.12.2-P1 <<>> google.com +trace
;; global options: +cmd
;; connection timed out; no servers could be reached

root: dig @8.8.8.8 google.com +trace

; <<>> DiG 9.12.2-P1 <<>> @8.8.8.8 google.com +trace
; (1 server found)
;; global options: +cmd
;; connection timed out; no servers could be reached

I checked whatever is possible, and it doesn't seem I have anything configured improperly on the firewall side.

One note, I have 2 interfaces:

WAN - just public IP
DMZ - static route to the corporate network via a separate router

This setup was working fine and suddenly users reported problems with DNS.
I thought in the beginning that it is dns forwarder issue, but then I realized that my PFSense is unable to resolve any addresses.

The router is hundreds of miles away from me so I have to do whatever is possible remotely.
Can somebody give me some advice, please?

Apparently, another corporate router CISCO ASA connected to DMZ was the troublemaker. After physical disconnect and reboot of that device, everything started to work fine again :-)
