Source | IP address of the host at the source of the connection
Source name | Name of the object (if any) corresponding to the source host.

#### Possible actions

Several search criteria can be combined. All of these criteria have to be met in order to be displayed, as the search criteria are cumulative.

This combination of search criteria can then be saved as a “filter”. Filters will then be saved in memory and can be reset in the Preferences module of the administration interface.

(Filter drop-down menu) | Select a filter to launch the corresponding search. The list will suggest filters that have been saved previously and predefined filters for certain views. Selecting the entry (New filter) allows the filter to be reinitialized by deleting the selected criteria.
Filter | Click on this button to: Select filter criteria (Search criterion). For the "connections" view, the criteria are the following: By address range or by IP address By interface By source interface By destination interface By destination port By protocol By user (grayed out if a host has been selected in the "hosts" view). For a value of exchanged data higher than the value specified with the cursor. According to the last use of the connection (only saved connections with a last used value lower than the specified value will be displayed). By rule name By IPS profile. By geographic source or destination. If only the Display all TCP/UDP connections (shut down, reset connections, etc.) checkbox is selected, the filter will display all connections regardless of their state as well as the associations in use. If only the Display all SCTP associations (reset, currently in use, shutting down and shut down) checkbox is selected, the filter will display all SCTP associations regardless of their state as well as the connections in use. Whenever both the Display all TCP/UDP connections (shut down, reset connections, etc.) and Display all SCTP associations (reset, currently in use, shutting down and shut down) checkboxes are selected, the filter will display all of the firewall's known connections and associations regardless of their state. If neither the Display all TCP/UDP connections (shut down, reset connections, etc.) nor Display all SCTP associations (reset, currently in use, shutting down and shut down) checkbox is selected, the filter will display only connections and associations in use. Save as a customized filter the criteria defined in the Filter panel described in the next section (Save current filter). You can save a new filter using the button "Save as" based on an existing filter or a predefined filter offered in certain Views. Once a filter has been saved, it will be automatically offered in the list of filters. Delete current filter.
Reset | This button cancels the action of the filter currently in use. If it is a saved customized filter, this action will not delete the filter.
Refresh | This button refreshes data shown on the screen.
Export results | This button makes it possible to download a file in CSV containing information from the table. Once a filter is applied, all results matching this filter will be exported.
Reset columns | This button makes it possible to reinitialize column width and display only columns suggested by default the first time the host monitoring window is opened.

#### "FILTER ON" panel

You can add a criterion by dragging and dropping the value from the results field into the panel.
