To help increase security in your perimeter network, we recommend that you deploy Edge Servers in the following way:

  • Create a new subnet from your perimeter network router for Office Communications Server.

  • Verify that traffic coming to the Office Communications Server subnet does not route to other subnets.

  • On your perimeter network router, configure rules to ensure that there is no routing between your Office Communications Server subnet and other subnets (with the exception of a management subnet that can include management services for your perimeter network).

  • On your internal router, do not allow any broadcasts or multicasts coming from the Office Communications Server subnet in the perimeter network.

  • Deploy the Edge Server between two firewalls (an internal firewall and an external firewall) to ensure strict routing from one network edge to the other.
