IAP external captive portal with proxy server

    Hi all,

     

    I am trying to use the external captive portal feature with IAP and ClearPass Guest.

    The issue I have is that we are using a proxy pac file to tell users to use the proxy server.

    Without the proxy configured, the users are redirected to the portal page

    With the proxy configured, the users are NOT redirected.

     

    Environnement :
    IAP version 6.3.1.4-4.0.0.5_43022
    Clearpass version 6.3.0.60730
     
    The pac file is hosted on the proxy server itself on port 80
    The proxy server is a Squid on port 3128
     
    It looks like the redirection on the IAP only works for connection on port 80 and 443 but not on port 3128.
    Is there a way to change that and redirect proxy connection to the portal ?
     
    I tried using the dest-nat with ACL but it doesn't work.
     
    Thanks for the help.
