Allows a client that did not create a remote bind to receive a primary inbound connection.
HRESULT EmulateClientBind( LPSOCKADDR ClientAddress, DWORD ClientAddressLength, LPSOCKADDR ProxyAddress, DWORD ProxyAddressLength, INT Protocol, REFGUID ProtocolGuid, IFWXConnection **piConnection );
|FWX_PROTOCOL_TCP||The request is for a TCP socket.|
|FWX_PROTOCOL_UDP||The request is for a UDP socket.|
This method should be called by a filter whose purpose is to enable a specific protocol. The filter uses this method when it needs to forward a primary connection made from an external source to a local computer that did not make a remote bind through the Firewall service. For example, this could be a local computer that is not a Firewall client.
This method will usually be called by a filter that is listening on some well-known port when it receives a connection. The filter decides (based on the source address, data exchange with the caller, a hard-coded address, and so on) that this call should be forwarded to some internal client.
The filter cannot use the BindForClient method because the well-known port is already in use and the connection was already made.
This method creates a connection object on which the caller can call the IFWXConnection::EmulateConnection method and forward the connection to the client.
Like other bind requests, any filter registered for the fwx_Bind_* events is notified about this bind and has an opportunity to deny it. It may also install a data filter. Other filters cannot emulate this bind because the caller is already emulating it.
