Explanation/Reference:
TCP-UDP packet filter
If you decide to remove the Outgoing policy, you must add a policy for any type of traffic you want to allow through the Firebox. If you remove the Outgoing policy and then decide you want to allow all TCP and UDP connections through the Firebox again, you must add the TCP-UDP packet filter to provide the same function. This is because the Outgoing policy does not appear in the list of standard policies available from Policy Manager.

The FireWatch page is separated into tabs of data that is presented in aTreemap Visualization. The treemap is a widget that proportionally sizes blocks in the display to represent the data for that tab. The largest blocks on the tab represent the largest data users. The data is sorted by the tab you select and the type you select from the drop-down list at the top right of the page.
