Ports to open in Checkpoint Firewall for Windows Clients / DC Active Directory Communications
Hello All -
Looks like we will be installing a new Checkpoint firewall between some of our Windows 10 Enterprise client machines and our Widows Server 2012 R2 Domain Controller soon. I wanted to do some homework to see what ports would need to be open to allow the required communications for Active Directory to pass through the firewall. With a few quick searches I did get some hits on DC to DC communications, but I'm just concerned with client to DC at this point.
Thanks!

MS is again bad at documentation. They write DC to DC, but the table holds all sorts of client2DC ports as well as seen in the description of the single items. ->You can use it.

Thanks for the links and clarifications! With the info you provided and the firewall logs themselves I should be able to narrow things down to the minimum needed. Thanks again!
