SupportOldFirewallClients Property of the IFPCClientConfigSettings Interface

The SupportOldFirewallClients property gets or sets a Boolean value that indicates whether the Forefront TMG computer supports Firewall clients running earlier versions of the Firewall Client software.

[C++]
HRESULT put_SupportOldFirewallClients(
	VARIANT_BOOL fSupportOldFirewallClients
);
HRESULT get_SupportOldFirewallClients(
	VARIANT_BOOL* pfSupportOldFirewallClients
);

Parameters

pfSupportOldFirewallClients

Pointer to a Boolean variable that is set on return to VARIANT_TRUE if the Forefront TMG computer supports Firewall clients running earlier versions of the Firewall Client software, or to VARIANT_FALSE if the Forefront TMG computer does not support such Firewall clients.

fSupportOldFirewallClients

Boolean value that indicates whether the Forefront TMG computer supports Firewall clients running earlier versions of the Firewall Client software.

Return Value

These property methods return S_OK if the call is successful; otherwise, they return an error code.

[Visual Basic]
Property SupportOldFirewallClients As Boolean

Property Value

Boolean value that indicates whether the Forefront TMG computer supports Firewall clients running earlier versions of the Firewall Client software.

Remarks

This property is read/write. Its value is initially set by the administrator during setup.

By default, Forefront TMG communicates with Firewall clients running the current Firewall Client software over an encrypted control channel through TCP port 1745. Forefront TMG can also support Firewall clients running earlier versions of the Firewall Client software, including Firewall Client for ISA Server 2000 and the Winsock Proxy client (from Microsoft Proxy Server 2.0), and Firewall clients running any version of the Firewall Client software on Windows NT Server 4.0, Windows Millennium Edition, or Windows 98, which send requests to UDP port 1745 and must use an unencrypted control channel to communicate with a Forefront TMG computer.

When this property is set to False (VARIANT_FALSE in C++), Forefront TMG listens for incoming requests from Firewall clients only on TCP port 1745. When this property is set to True (VARIANT_TRUE in C++), Forefront TMG listens for incoming requests from Firewall clients on both TCP port 1745 and UDP port 1745. An encrypted control channel is used for requests received on TPC port 1745 provided the EnableControlChannelEncryption property is set to True (VARIANT_TRUE in C++) (the default value), and an unencrypted control channel is used for requests received on UDP port 1745.

This property can be accessed through the Allow non-encrypted Firewall client connections check box in Forefront TMG Management.

Client Requires Windows Vista or Windows XP.
Server Requires Windows Server 2008.
Version Requires Forefront Threat Management Gateway (TMG).
IDL
