This may not be a protocol control issue, so if its not I'll repost in the correct forum.
A few of our staff connect to a Cisco sonet, via the Cisco CTC software, which is java based (ballpark ver 1.5.0-x, more current versions of java do not work).
With the Untangle VM running, we can browse to any of the shelves, launch the application, but during its discovery process, it hangs. Now, if I stop the Untangle VM, the CTC software works fine. I look in the Protocol Control event log, and see nothing related to this being blocked. Same goes for Intrusion Detection, firewall, or even Web Filter.
I'm kind of scratching my head about which part of Untangle is knocking down the CTC software. Could it see the older version of Java as a vulnerability? I'm not really for sure where to look, since I see nothing related to it in any of the event logs.
