The FwpsRedirectHandleCreate0 function creates a handle that connection redirection functions can use to redirect connections to a local process. For more information about redirection, see Using Bind or Connect Redirection.
Note FwpsRedirectHandleCreate0 is a specific version of FwpsRedirectHandleCreate. See WFP Version-Independent Names and Targeting Specific Versions of Windows for more information.

redirectHandleA pointer to the variable that receives the handle.
The FwpsRedirectHandleCreate0 function returns one of the following NTSTATUS codes.
| Return code | Description |
|---|---|
| STATUS_SUCCESS | A redirect handle was successfully returned. The variable that the redirectHandle parameter points to contains the handle. |
| Other status codes | An error occurred. |
A callout driver calls the FwpsRedirectHandleCreate0 function to create a handle that can be used to redirect connections.
For more information about redirection, see Using Bind or Connect Redirection.
Your callout driver should call FwpsRedirectHandleCreate0 once and cache the handle so that it can reuse the handle.
Before an Application Layer Enforcement (ALE) connect redirection callout can redirect connections to a local process, it must obtain a redirect handle with the FwpsRedirectHandleCreate0 function and put the handle in the FWPS_CONNECT_REQUEST0 structure. The callout modifies the structure in the classifyFn for the ALE connect redirect layers.
After a callout driver has finished using a redirect handle, it must call the FwpsRedirectHandleDestroy0 function to destroy the handle.
