      The actual network as in real physical network should not matter public or not... The ZT network does need to be trusted though, and even that should matter on the client side because you aren't sharing your just accessing.

        When having a problem open a CMS prompt and ping the severname... Check the ip ita resolving to... It should only use the ZT ip...

          @Dashrender I just connected and pinging the server results in an IP address that isn't even on my network. ZeroTier or real LAN.

            Exactly this. The ZeroTier network should be reporting as domain.

              My LAN is 172.16.x.x

              ZeroTier is 192.168.191.x

              When I ping the DC I get 198.105.244.130

                Sounds like you have a DNS issue. You might not be able to use short NetBIOS type names.. you might have to move to FQDN instead.

                For example, if you're at StarBucks and the DHCP server gives a suffix of starbucks.com out with the IP, and you ping server1, your system might be pinging server1.starbucks.com instead of server1.yourdomain.com

                  @Dashrender For this machine it does resolve to a FQDN just with the 198.105.244.130 address instead of the ZT IP of the DC

                    Are you sure your ZeroTier addresses are what you think they are?

                      @JaredBusch I hope so. I was looking at ZT Central when I typed it out 🙂

                        man, time to just double check... ipconfig in same session you ping server1. Where could that bizzaro IP could have come from? either ZT or DNS, or Hosts file.

                          Are you sure that you set the auto assign correctly?

                            @Dashrender Hmm - I just ping'd from my laptop (Mac OS X) and got the same address that I got on the other laptop. Here is the screenshot from my ZT Center.

                            http://i.imgur.com/LfOdpLn.png

                            Here is the info from the machine

                                Ok, just tested this a little more.

                                Laptop off the LAN.
                                Ping from laptop to DC by name = ping resolves over ZeroTier IP.

                                C:\Users\xxxadmin.xxx>ping xxxdc01
                                
                                Pinging xxxdc01 [10.202.3.11] with 32 bytes of data:
                                Reply from 10.202.3.11: bytes=32 time=42ms TTL=128
                                Reply from 10.202.3.11: bytes=32 time=42ms TTL=128
                                Reply from 10.202.3.11: bytes=32 time=45ms TTL=128
                                Reply from 10.202.3.11: bytes=32 time=43ms TTL=128
                                
                                Ping statistics for 10.202.3.11:
                                    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
                                Approximate round trip times in milli-seconds:
                                    Minimum = 42ms, Maximum = 45ms, Average = 43ms
                                

                                But a ping from the DC to the device returns the devices local IP not the ZeroTier IP.

                                C:\Users\xxxadmin>ping dt-backup-lapto
                                
                                Pinging dt-backup-lapto [192.168.1.8] with 32 bytes of data:

                                Request timed out.
                                
                                Ping statistics for 192.168.1.8:
                                    Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),
                                

                                Here is what ipconfig returns on the remote laptop.

                                C:\Users\xxxadmin.xxx>ipconfig

                                  The DC is the image on the right. the laptop is the image on the left.

                                    Did you check the client for viruses/rootkits? Had a similar issue where I was getting a public IP return when querying an internal DNS name; turns out the PC had a DNS hijack virus/rootkit on it returning all sort of odd results.

                                      @JaredBusch Your screenshot brings up a question that I have been having since my Pertino days. Does the ZT NIC go first on the priority? I was getting some mixed messages from Pertino on the priority of things.

                                        Yes it does. But since it should have no gateway, there will not be any issue with it generally.

                                          @WLS-ITGuy That said, I had issues with Pertino routing all traffic over itself and had to manually update that setting to have Pertino lower priority in order to prevent it.

                                          But the difference I have seen with ZeroTier is that even if it decides to route over the ZT adapter, my ping times are still 1ms in the office.

                                          With Pertino , that was not true and it lagged the hell out of my inter server communication.

                                            This matches up with what I've seen in my home office as well.
