      Also, if I ping another server from off site I get this:

      i2l62Y5.png

      WOW - how does that happen? What is returning that IP address? I wonder if the coffeehouse server is returning bad info?

      You probably need to ipconfig /flushdns ?

      But where did the 198.105.x.x IP come from? that is not anywhere on the OP's network (that we know of). When I ping that FQDN here I get could not fined host.

      Good point... Could it be from an old web host, or an old internal DNS entry for something?

      Sure it could be, but if pinging that server while in the office gets the correct IP, you'd assume the DNS servers in the office would be giving the same response in all places, internal and external.

        Except in the case of the end-user's machine not actually hitting the internal DNS, maybe?

          I don't know where that 198.105.x.x ip is coming from which is why I asked about the DNS/Office 365 thing.

          It is not an IP here on campus that is for sure.

            Sure, but if the user isn't hitting an internal DNS, where would that address come from at all? I would expect it to simply fail, or get a *.wls.wels.net reply back, which isn't happening when I ping, so no reason to believe that would be happening to the home user.

                    makes me wonder if the router at the coffee shop was taken over and is doing bad things...

                    Was that IP obtained while at the coffee shop? or did I miss it and it was really someone at their home?

                          The user has IPv6 DNS enabled as their first DNS server at home.

                          0_1462911919117_upload-2982eb2a-27ab-4425-9869-c34ca4ee38b2

                          Turn off IPv6 on their main network conneciton.

                            What do they have for DNS servers at home? Their ISP? I've seen many ISPs (Cox does this) if you put in a bad address, you get redirected to a bad website request page hosted by Cox instead of getting an invalid domain name as you might rather have. They are trying to making things more understandable for consumers, sadly it just screws us instead.

                            Have you home user change the DNS provided by their router (if possible) to Google's 8.8.8.8 and 8.8.4.4 and try again.

                              If you are off-site and your DNS server returns the internal IP, stuff still ain't gonna work. 😞

                              This also goes back to what I said. You do NOT want to do this unless you are 100% ready to manually update your on premise DNS server manually to have every ZeroTier IP address listed.

                                          Most likely it is his ISP hijacking the bad DNS results and will show a search page if he were to use a web browser.

                                            Except in the case of the end-user's machine not actually hitting the internal DNS, maybe?

                                            Sure, but if the user isn't hitting an internal DNS, where would that address come from at all? I would expect it to simply fail, or get a *.wls.wels.net reply back, which isn't happening when I ping, so no reason to believe that would be happening to the home user.

                                            F[moderated], I said it. It is coming from his primary DNS like it should.

                                            Most likely it is his ISP hijacking the bad DNS results and will show a search page if he were to use a web browser.

                                            I concur.
