      We have a wireless controller that keeps the Secured and Student VLANs separate. I have access rules that allow certain IPs/ports through to the Secured side.

      If that helps.

      DNS on the public side should do the trick, right?

      What do you mean? change the Public access DHCP server to give only a public DNS server? yeah that along might solve it, assuming his router can do hairpinning if required.

        Not what I meant, I meant a DNS server that he runs himself, but that is for the public portion of his network. That why he could hand out whatever data he wanted there.

          Let me see if this helps explain my setup here.

          172.16.0.60 is the HP Core Switch which acts as the router. Which also has 172.17.0.1 and 172.18.0.1 as Virtual IP's.

          4 VLANs - 172.20.x.x not in use.

          Students are reporting that when they go to https://mailhost.wls.wels.net/owa on campus that it doesn't load. MOre often than not they get this error:

          mailhost.wls.wels.net unexpectedly closed the connection.
          Try:
          Reloading the page
          Checking the connection
          Checking the proxy and the firewall
          ERR_CONNECTION_CLOSED
          ReloadHIDE DETAILS

          However, if they go to https://wls-exchange.wls.wels.net/owa it works fine.

            This tells you that your DNS is the issue.

            From a student device (or a test device on student network) what do those two domain names resolve to?

              WLS-Exchange resolves to the internal IP of the server.

                  oh, gotcha.. for him to have two completely independent DNS systems, one for corporate, and one for Guest network.

                    WLS-Exchange resolves to the internal IP of the server.

                    There is your problem.

                    Exactly - if you want to continue with your current network topology, you'll want to create records specifically for use in the Public WiFi space that are different than those used for your internal network space.

                    The reason for this is that your internal devices all are on both ZT and your internal network, so they won't care if they receive an internal or ZT IP, but your Public network doesn't know about ZT, therefore it will fail everytime your DNS server gives out a ZT IP address.

                    FYI - you can register the same host name to more than one IP, so your hostname mailhost can resolve to an internal IP and ZT at the same time, and this is what causes most of these problems.

                    But creating a unique A record for use on the Public network, you don't have to worry about the Public network getting ZT addresses.

                      This type of issue is why I repeatedly stressed that you had to plan everything out very carefully if you were going to start messing with DNS.

                        And why I recommend using a ZT Bridge... so you don't have to mess with DNS, lol.

                          OK. Mailhost.wls.wels.net already had a A record of 172.16.0.14 (Exchange Server IP) but to get those on the ZT network to see the server I had to create another one with the ZT IP. I did not create a 2nd A record for wls-exchange.wls.wels.net. I don't see how I can create a unique A record for the Public Network when it goes through the same DNS as the other two networks.

                            You can't. That's why I mentioned having a different DNS server for that network.

                              So I would be making an entirely separate network for the Student/Public network on the same internet pipe?

                                Time for a dumb question... If we know that they have a URL that works on the Student/Guest side... why not just have them use that URL?

                                  By unique, I mean fully unique. corporate/ZT network use mailhost, the public wifi uses mailhost1 or whatever you create. it's unique for use by the public network.

                                    Of course, this presents roaming problems, if a device on the public network later joins the corporate network, it might not work any more.

                                      This is what I have going on for now as https://wls-exchange.wls.wels.net/owa doesn't work off campus. So I have them go to that on campus and mailhost off campus.

                                        I don't see how I can create a unique A record for the Public Network when it goes through the same DNS as the other two networks.

                                        You can't. That's why I mentioned having a different DNS server for that network.

                                        So I would be making an entirely separate network for the Student/Public network on the same internet pipe?

                                        Time for a dumb question... If we know that they have a URL that works on the Student/Guest side... why not just have them use that URL?

                                        This is what I have going on for now as https://wls-exchange.wls.wels.net/owa doesn't work off campus. So I have them go to that on campus and mailhost off campus.

                                        This just wraps you back around to either using the public DNS servers for the Public WiFi, or setting up a separate DNS server for that network.

                                          Why if I go to the mailhost or wls-exchange address does it work on the Secured wireless but if a student is connected it doesn't? If both VLAN's use the same DNS shouldn't DNS resolve to the local IP before trying to go out to the ZT IP?

                                            So I should just set in the Scope options 8.8.8.8 and 4.4.4.4 as the DNS and see if mailhost works on the Student/Guest network?
