Apologies if I have not provided enough detail.
I have a SharePoint 2013 server running inside our organisation. Authenticated users access this through https and a certificate has been installed. This work fine and users can directly access sites without any further prompting of username or password.
I now want to let my laptop users access the same sites from outside of the organisation using the the https://
site name. I have configured a 1to1 NAT on our firewall and created an external DNS entry pointing to the IP address that is natted to the internal SharePoint server.
I can see on our firewall that traffic is being sent but the laptop user receives a page cannot be found, it looks like an authentication issue.
Can someone please assist in how I should set this up using the simplest method available, still using https but without receiving a challenge box as they are already authenticated to their laptop using their AD credentials when outside of the organisation. I do not need any user who is not registered in AD to have access.
