WSALookupServiceBegin, WSALookupServiceNext, and WSALookupServiceEnd are implemented, but only resolve queries that would translate into queries by using the gethostbyname, gethostbyaddr, getservbyport, or getservbyname functions. However, for connections made through the Firewall service, Resource Reservation Protocol (RSVP) reservations will not pass through the service. Forefront TMG installs an LSP that supports Quality of Service (QoS) requests. However, using a blocking or non-blocking call to recvfrom, the application will see the actual from address of the Internet host that originally sent the packet. The Winsock API will work, but for a remote socket, the from address that the application will receive is the address of the Firewall service internal socket. However, the following limitations should be noted:

The remote Forefront TMG Client software supports basic Winsock 2.0 functionality.

The reply is then processed by the Forefront TMG Client LSP, and translated to a Winsock error code in case of failure. The Firewall service checks the request against the Forefront TMG policy, processes the request on behalf of the client, and returns a reply through the control channel. When a Winsock function call is redirected to the proxy, the Forefront TMG Client LSP sends a request through the control channel to the Firewall service and waits for a response. The control channel connection is established the first time that it is needed. The Forefront TMG Client LSP communicates with the Firewall service by using a dedicated connection to TCP port 1745, called the Forefront TMG Client control channel. Remote calls are redirected to the Firewall service. Local calls are passed to the original base service provider. When a client application calls a Winsock function, the Forefront TMG Client LSP intercepts the call and determines, based on the arguments specified in the call and the configuration settings provided by the Firewall service, whether the call is local or remote. All Winsock applications running on a Forefront TMG Client computer use this LSP transparently.

When Forefront TMG Client, which supersedes Firewall Client, is installed and enabled on client computers in a protected network that send requests through Forefront TMG servers, Windows Sockets (Winsock) applications running on these client computers can send requests to remote destinations transparently through the Microsoft Firewall service.įorefront TMG Client includes a dynamic-link library (FwcWsp.dll) that works as a layered service provider (LSP) on top of the original underlying base service provider.
