About networks

Microsoft Forefront Threat Management Gateway networks are created and configured to model your physical corporate networks. Forefront TMG constructs a number of predefined networks during installation, and you can also create custom networks. Typically a network exists for each network adapter installed on the Forefront TMG server. For more information about the predefined networks, see the following topics:

• Internal and perimeter network properties
• External network properties
• Local Host network properties
• VPN Clients and Quarantined Clients network properties

Before modifying or creating networks, be sure that you understand how Forefront TMG implements the network model. For more information, see Before creating networks.
