I have a domain controller with secure LDAP available on port 636
However we have internal dns for our outside domain setup to be remoteDC.ourdomain.com
that hostname is set to direct to the internal IP and is opened through external firewall to allow connection into the internal Domain Controller.
Using LDP.exe internally I can connect to the remoteDC.ourdomain.com but externally cannot, even though firewall rules are there to allow.
Would this have to do with any certificates or the remotedc.ourdomain.com not matching the internal domain controller called DC01?
