WFP connect redirect to local proxy RRS feed

  • Question

  • Hello, everyone! 

    I am implementing a WFP callout driver to redirect connection to local user mode proxy. Doing inline redirection as per

    As proxy service is in user mode, after getting the redirected connection, I fetch the redirect record and redirect context and the associate context. while i do this, do i need to be in sync with driver's call out function! 
    Driver callout function gets executed and calls FwpsReleaseClassifyHandle at the end. 
    User mode code query redirect record & context and associate the context later. Is that a problem!

    I am getting connection redirected to my local service. To forward the connection to original destination, if set the redirect record to outbound socket, I see webpage is not loading and its getting timed out. 
    Without setting the redirect record, webpage is loading without any issue. This looks really strange. can someone explain this behavior.
