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.

@alex.olynyk said in Certbot:
@Dashrender our mail server is hosted POP so that's accessed via mail.roseradiology.com
no internal IP address for thatThen 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.

@JaredBusch i just did this and it still wont work. when i ping www.rose and mail.rose it returns the same IP. Added both in local DNS. www works on the inside but not mail
owncloud and pacs work on the inside but no mail
-
-
now only owncloud and pacs are working on inside
www and mail are not working
cause they have the same IP when i ping? how do i fix?

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?
-
-
@Dashrender 11 centers
-
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?
-
true, but those are the only things not working on the inside
pacs and oc work -
@Dashrender www and mail dont work on the inside

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?
-
www IP works from the inside, flushed DNS
-
rebooted the server im remotely connected to, nothing
-
@alex-olynyk check your host file
-
cleared arp cache
-
nothing in hosts file
