I need a Networking, DNS or DNS related experience person to solve my issue, I believe this to be the issue (although I’m not certain).
EQUIPMENT:
-pfSense 2.3.1-RELEASE-p5 (i386) FreeBSD 10.3-RELEASE-p3.
-Time Warner Cable (TWC) supplied router Arris TG1672G in bridge mode.
-Netgear Router Nighthawk X6 R8000, again in bridged mode and only using wireless features. I use 4 of the available ports to connect other devices (laptop, printer, local server).
ISSUE:
I can not connect to certain domains hosted on a off-site physical server running linux CentOS, which coincidentally is owned by me. I can access the internet and browse a number of other public websites on my desktop, laptop and iPad.. I can successfully connect to the plesk control panel on the server, however I cannot connect to any website that resides within it. Really weird.
THINGS I’VE TRIED:
-Verified that the domains are working. They can be accessed from a cell phone using the providers data rather than my wireless network.
-Reset the cache in Safari, Mozilla.
-Reset the cache in pfSense.
-Reset and factor reset numerous times the TWC router, pfSense router, and the NetGear Nighthawk.
-Performed ping test from laptop using Terminal on Mac and all tests returned successful.
-Removed all pieces of hardware then connected laptop directly to TWC router and was SUCCESSFUL in connecting to the domains in question. This is why I believe it might be related to pfSense settings.
WHAT COULD HAVE CAUSED THIS ISSUE:
The system had been working correctly up until last week. The only change that was made was that I upgraded the pfSense to v 2.3.1. Prior to upgrade I had the version that did not have the new GUI design. Could this be the reason? If so, how to roll back changes to confirm or deny this hypothesis?
WHAT I THINK MIGHT BE THE ISSUE:
I think this might be related to a DNS issue. Although, truth be told, I’m not at all experienced enough to understand the technical details of how DNS works.
I have SSH access to pfSense as well as the GUI.

I have been using pfSense professionally for over a year. Before that used FreeBSD (which is what pfSense is based on). Also experience setting up and maintaining DNS infrastructure for multiple networks.
Please feel free to chat with me about this project.
Hello. I have some experience with pfSense and big experience with clean FreeBSD 7-8-9.
I don't understand some some moments:
1. The network topology. Where Is located pfSense? Between TWC and Netgear Router?
2. Need more information, commands output for ping, telnet, dig, nslookup and etc.
Please, contact me, when I can help you.
