• Create a new subnet just for the Microsoft Lync Server 2010 Edge Servers.
  
  
• Enhance the security of the routing rules for access to that subnet (disable broadcast, multicast, and traffic to other perimeter network subnets).
  
  
• Refrain from changing the service account under which edge services run.
  
  
• Read and use the information in Protecting the Edge Server Against DoS and Password Brute-Force Attacks in Lync Server 2010 at http://go.microsoft.com/fwlink/?LinkID=214180.
