SNS 3.x versions have reached End of Maintenance since July 1st, 2024.
We recommend that you update your SNS firewalls to a version with maintenance to guarantee the protection of your infrastructure.

# Presentation of the configuration screen

The interface configuration window consists of 3 sections:

- The directory of interfaces: the appliance’s interfaces are presented sorted in the following order: Bridge, Interface, VLAN, Modem according to the selected view. Clicking on an interface allows viewing its configuration. It is also possible to use the search engine to look for a specific interface. (Example: by typing “br”, all bridges will be displayed).
- The configuration panel (central panel): by clicking on an interface in the directory, its configuration will appear in this panel.
- The toolbar: this bar allows:

- Adding or deleting interfaces (bridge, modem),
- Expanding or collapsing the folders in the interface directory,
- Selecting one of 3 views: “Mixed view” which is the default view and which corresponds to a logical representation of the interfaces (that is, bridges first (they make up the root node), interfaces, VLANs (attached to the interface or the bridge), then modems). “Group by physical port” and “Group by address range” allow filtering according to the desired interface and checking its use.

## Directory of interfaces

The appliance’s interfaces are indicated in the directory.

### Drag & Drop

Dragging and dropping an interface modifies its configuration (its relationships and address range). If a drag & drop operation is authorized, a green tick will appear. Otherwise, if the move is prohibited, a red circle will be indicated.

When an interface is detached from a bridge, a window will appear, allowing the address range to be entered.

The following moves are allowed:

Bridge/Interface | From | To
Ethernet Interface | Bridge | Root
Ethernet Interface | Bridge | Another bridge
Ethernet Interface | Root | Bridge
VLAN | Ethernet Interface | Another Ethernet interface
VLAN | Ethernet Interface | Bridge
VLAN | Bridge | Another bridge
VLAN | Bridge | Ethernet Interface
Modem (PPPoE) | Interface | Another interface

### Searching for interfaces

An interface can be found more easily with the search field.

Name, Address, Type, Comments, Hostname (DHCP), Physical MAC address, Gateway (routing by interface). Searches are possible in the following fields of the interfaces:

Example: you can search for an interface by indicating its name or even the address of its gateway.

To validate a search, simply click on Enter. To delete a search, click on the cross to the right of the search field.

### Identifying interfaces

Each interface has its own icon for quicker visual identification. This icon also allows identifying whether the interface has been enabled or disabled. If it has been disabled, the icon and the name of the interface will be grayed out.

Ethernet interfaces have a real name (ex: "Out") and a technical name (ex: "0"). The physical port is displayed in brackets after the name of the interfaces.

## Toolbar

Add | This button allows you to open the bridge, VLAN, modem or GRETAP interface creation wizard. It also allows converting an interface into a link aggregate.
Delete | This button allows you to delete an interface that was previously selected in the interface directory. Ethernet interfaces cannot be deleted.
Collapse | This button allows collapsing all folders in the interface directory.
Expand | This button allows expanding all folders in the interface directory.
Mixed view | 3 views are suggested: Mixed view, Group by physical port (interfaces are grouped by port. For each port, interfaces and VLANs are indicated), Group by address range (interfaces are separated according to their address range. If the interface contains an address + an alias, in this case, it will appear twice in the directory).
Show all | 6 filter options are available: Bridge, Interface, VLAN, Modem (Dialup), GRETAP interface, Show all.
Check usage | If you click on this button after having selected an interface, the results will appear in the directory of modules. If you delete an interface, a check will be performed in order to warn the user about configurations that use the interface he wishes to delete. If the interface is in use, the following message will appear: “Warning, this interface/bridge is being used by one or several modules. Removing it will make the firewall unstable." You can either force the deletion, check its usage or cancel. If the check does not turn up any results, the message: “Delete this interface?” will appear.

NOTE

An external 3G modem can now be connected to the USB port.

NOTE

Renaming an interface does not migrate references to it especially in configuration items that use generated objects such as "Network_in". A warning message appears when an interface is renamed.
