We have been using the Watchguard authentication applet to enable users to use OWA externally for while without a problem. However, one of our users now needs to use this from behind a proxy server on another network and this does not work.
The authentication applet loads in and allows him to sign in (giving the "Authenticated" signal) but the Watchguard still does not give him access to the ports he should be able to use. He can use it fine when it is not behind a proxy server.
Does anyone know how to fix this?
Cheers.
