I am currently planning to set up our first Direct Access server (Windows Server 2012 R2). I will be in our firewall DMZ and we will be using the IP-HTTPS listener.
For the Internet facing rule only TCP 443 inbound/outbound is sufficient but for the LAN facing rules (not talking about the Windows server firewall) what would be the recommended firewall rules for a Direct Access server? Is there a best practice guideline
to follow for this? Appreciate any advice or comments. Thank you.
