C. Configure Direct Access to send Domain Name System (DNS) queries for the access, webconf, av, _sip._tls, and meeting URLs and all other Lync services to external DNS.
D. Limit service to selected IP addresses in the Topology Builder.
Correct Answer: BC
Explanation/Reference:
DirectAccess, Its Microsoft new Remote connectivity solution where users on the Internet get Intranet connectivity to their corporate network without installing any client or initiating any software like old traditional VPN.
Microsoft DirectAccess is purely based on IPV6 and Lync 2013 is fully supporting IPV6 and Lync 2013 clients using DirectAccess should work without any problem. If any one encountered problems making Lync calls or connecting to Lync on a DirectAccess Computer then you need to ensure that IPV6 is enabled on the Lync 2013 Server as per the below image.
This can be achieved as follows:
Open the Lync 2013 Topology Builder from an old file or download the topology 1.
Edit the properties of the Lync server and in the General Properties ensure that IPV6 2.
is enabled.
These settings need to be published from the Action Menu – Topology – Publish 3.
Now you can enjoy Lync 2013 over DirectAccess Connection.
* From scenario:
The company wants to allow only authorized employees to connect remotely. All remote users will use a secure method when remotely connecting to the network and the Lync environment.
