Squid3 (3.1) Reverse Proxy & Exchange EWS attachments



  • Hello,

    I run pfSense 2.1.4 with the Squid3 (3.1) package as Reverse Proxy for several Web Services including Exchange 2013. Everything works as expected, except Exchange Web Services (EWS) for Mail clients.
    They work too, except sending attachments greater then about 12kB, I get a HTTP/401 unauthorized.

    As I said, everything else works (Active Sync, OWA, OAB).

    Can anyone help to debug this further?

    Thanks!
