Configure Firewalls

Topic Last Modified: 2009-01-23

Configuring firewalls includes configuring both of the following:

• The internal firewall between the perimeter network and your internal network.
• The external firewall between the perimeter network and the Internet.

How you configure your firewalls is largely dependent on the specific firewalls you use in your organization, but each firewall has common configuration requirements that are specific to Office Communications Server 2007 R2. For a list of required firewall settings, see Firewall Requirements for External User Access. In addition to this information, follow the manufacturer's instructions for configuring each firewall.
