      @StrongBad The only thing I can think of is speed? Maybe it's a bit faster? However many routers have loopback NAT, so no difference there.

      The term you are looking for is HAIRPIN NAT.

      Personal opinion incoming: You NEVER want to rely on HAIRPIN NAT, ever.

      For most companies, DNS is not something that changes very often. It is much easier to handle entering DNS information both into both the internal and external DNS servers.

        I tend to agree with JB on this one.

          @Dashrender our mail server is hosted POP so that's accessed via mail.roseradiology.com
          no internal IP address for that

          Then for that one you will still use the external IP, but you WILL have to put in a record in your local DNS.

          I have lost track of how many times you have been told this is the correct answer.

          Hey, listen to JB on this one you should.

                  I hate to ask, but please post a pic of the command prompt where you are pinging those addresses.

                    I'm not sure what you mean that they have the same IP? your picture of your DNS shows you set them up with the same IP, so that is to be expected.

                      WOW, assuming all the NS (DNS servers) are Active Directory Domain Services (ADDS), you have a lot of them, are you a huge company?

                            OK that matches what you setup for DNS for WWW and mail.

                            And it matches what I get when I ping those from outside.

                            So what's the issue?

                                  from any computer? Try clearing the arp cache or rebooting and see what you get.

                                    If you open a browser and put the IP address into the line instead of the name www.roseradiology.com, does it work?
