I have a Watchguard firebox 700. In an attempt to allow users to access OWA, I setup http proxy to the server in the firewall. It workd fine, however, users could no longer visit some harmless, work related sites, or even download pdf files. They get a watchguard error message, so I know that it is the culprit. The funny thing is, I removed the http proxy and rebooted the firewall, but the restrictions are still there. Anything to do with Java, active x, pdf, is all blocked. I have searched all through the watchguard and cannot find where any rstrictions could be.
