Local Host network properties

Applies To: Forefront Threat Management Gateway (TMG)

Local Host Network Properties

The Local Host network represents the Forefront TMG firewall. It includes all IP addresses bound to all network adapters on the Forefront TMG computer. You do not explicitly define IP addresses on this network. Addresses are added automatically as they are defined on network adapters, including any wide area network (WAN) adapters that are created for VPN connections. Unlike other networks, addresses in the Local Host network are not mutually exclusive. In other words, addresses in the Local Host network will also exist in other networks.

All traffic that comes from the Forefront TMG firewall, and explicitly to the firewall, is considered to have passed by way of the Local Host network. During installation, a network rule is created to route traffic between the Local Host network and all other networks. You cannot manually modify or delete the Local Host network.
