Hi,
For Untangle to filter traffic it needs to be in the line of traffic as in image 1566.
If it is a small network you can use the Re-route technology.

Re-route is just that. it fools the client to speak to the re-route server insted of the gateway.
But i am having a hard time to understanding you.
