I have an online portal that communicates with our 2008R2 AD server. The portal is used as a self service password changing/reset help desk. I am moving the self service portal it to another subnet and on another interface of our firewall.
The ports found here: https://technet.microsoft.com/en-us/library/dd772723(WS.10).aspx
Must all these ports be open on the firewall for the portal to communicate its password change requests with AD? Or just certain ones?
