      Network Configuration = ISP (ATT) --- pfSense ---- Unifi Switch ---- Clients via Ethernet or Wifi APs

      Something happened on Tuesday night where all of a sudden, I was no longer able to connect to the internet. Prior to that date, pfSense has never had an issue running gaming consoles, a couple of servers, IoT for Home Automation, etc for over a year.

      Since then I have tried restoring from the backup configs I have taken over time after each update was made to the config (e.g. updated the config to get plex to work, updates for getting XBOX live to work, etc). I have tried reinstalling pfSense and using a default setup. I have purchased a new switch thinking a power surge messed up the switch (Cisco SG1 10-16HP was the original switch). I went back through the bridge mode setup to validate maybe ATT pushed out a software/firmware update that messed up the setup. None of these helped me to hit an external site such as google.com.

      Configuration information:

      • WAN rules are default with blocking private networks and block bogon networks
      • LAN has the anti-lockout rule, default allow LAN to any rule, and Default allow LAN IPv6 to any rule
      • DNS Resolver is enabled while DNS forwarder is not

      In addition, below is some additional information that I found when testing:

      • I can reach internal servers on the network
      • On my phone with mobile service turned off I am able to get to LinkedIn, Netflix, and YouTube.
      • I'm not able to access these same sites on my laptop either through WiFi or Ethernet.
      • I'm able to ping 8.8.8.8 and google.com from my laptop
      • I'm able to download packages via pfSense such as ntop

      Extremely frustrating that I have not to figure this out either reviewing the different posts with similar problems or just by following the instructions I created for the entire install / configuration process.

      I would be extremely appreciative for any help as we are going into day 4 with this weird connectivity issue (kids and wife are not happy and I'm not happy because I can't figure it out).

      Thanks in advance all!

        This may be a DNS issue. You did say that you could resolve google.com but that might have been cached.

        Can you do a lookup on any domain you haven't been to in at least a day, like linuxmint.com or xkcd.com? Always start with ping and DNS.

        I have to go but here is the connectivity guide & video which has pretty much every reason you can't connect.

          I'll definitely watch the video - appreciate that link. Its a long video :)

          Yes, I am able to ping linuxmint.com and xdcd.com via cmd.

          The results of those tests are shown below:

            I went back through the video and saw some other posts on the forum that gave me other ideas to check. Gateways seem to be a common problem in some of the posts I was reviewing where people were setting them.

            It looks like I don’t have one set based on the below under my LAN interface:

            Below is a screen shot from System – Routing – Gateways in case I messed something up

            Below is the current status by going to Status – Gateways

            I have automatic outbound NAT enabled/selected

            While I mentioned the firewall rules I have set on the WAN and LAN, I thought I better show them in case my noobness screwed something up

            You guys are my last hope to figure this out as I have reinstalled the software on the box now twice and tried factory settings reset, but nothing appears to change.

              You can resolve DNS and you can ping, which tells me that general connectivity isn't the problem.

              Please refresh me: what is the current state of your issue and what are you not able to do again?

              By the way, General Discussion isn't meant to be a support forum. It to talk about things in general. Support requests of a general nature would be better off in General pfSense Questions where it will get a lot more eyeballs and replies than here.
