DNS lookup failing
-
Hoping someone can help-
My pfsense install was working and all of a sudden it stopped. I found out that the ISP that I use cycles their two DNS servers, however I have both listed in the general settings. Now I can ping the two server IPs just fine, but when I try to resolve a name it cant(through the webgui and a PC connected to the LAN). I can use the direct IPs and everything is fine, just can't resolve names???
Can someone help?

Might want to just switch to better DNS servers and give up on your ISP's offerings. I use OpenDNS but there are a lot of other good free ones available too.

It did not seem to be the actual DNS service as I was able to do the following:
1. Laptop wired connection to the LAN via the switch
2. Laptop has static IP on the same segment as the LAN
3. Able to open a shell and ping LAN interface successfully
4. Able to ping WAN interface successfully
5. Able to ping DNS server IP address successfully
6. Able to ping google's IP address successfully ( i.e. ping 173.194.75.103 )
7. Unable to ping google using name ( i.e. ping www.google.com )Likewise if I open a browser and manually enter 173.184.75.103 I'm taken to google. If I use 'www.google.com' I get the 'can't load page'

seems to contradict @jffrysrn222:

What is your PC using as its DNS? What do you want it to use? (DNS = Domain Name Service, the service that translates host names to IP addresses.)

at results do you get on your client computers if you try running nslookup or dig?
Here 172.16.0.1 is my pfSense system and my updstream DNS servers are OpenDNS:
