RE: [ActiveDir] Which ports to open in the DMZ to communicate with AD & SQL...

[Bernard, Aric]

I agree with Phil – I think using an ISA (or other reverse proxy solution) is the best way to go given your constraints.   Using a reverse proxy solution allows you the following: Keep you Sharepoint server behind the firewall, yet make it accessible to external clients as if it was in the DMZ. Restrict your [additional] holes through the firewall to only that needed by the reverse proxy solution to interact with the Sharepoint server (port 80).   BTW - this scenario is becoming extremely common.  The next common addition you will see to this will likely be the use of ADFS to provide an identity trust bridge between the internal forest and a partner forest (or other identity system).   Regards,   Aric Bernard   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Phil Renouf Sent: Wednesday, September 07, 2005 9:20 AM To: ActiveDir@mail.activedir.org Subject: Re: [ActiveDir] Which ports to open in the DMZ to communicate with AD & SQL...   I would look at putting the Sharepoint server on the internal network and deploy an ISA server in the DMZ and use Web Publishing or Server Publishing to get your external clients access to the site. If you want to open access from the DMZ to your AD Forest your firewall will be swiss cheese from all the ports than need to be open.   If you absolutely HAVE to then I would prefer to look at using IPSec for communication between the Sharepoint box and your DC's. That leaves you only needing the IPSec port open and not the very large number of ports to support AD communication.   http://support.microsoft.com/kb/q179442/   Phil   On 9/7/05, Jason B <[EMAIL PROTECTED]> wrote: Because this will be a sharepoint server for clients.  Regardless, that decision has already been made and I don't have any input into it.
