Action required: Apply the fix for SNS firewall disks.
Please follow the procedure described in the How to update my SSD Firmware - Stormshield Knowledge Base article (authentication required).
The Interfaces module makes it possible to manage, add or delete “network interface” network items. These represent physical or virtual communication devices between the various networks that pass through the firewall.
The module window consists of a grid containing:
- The list of the firewall's interfaces and information about them.
- A taskbar: it shows the various possible operations that can be applied to interfaces.
- The control panel of each interface: appears when an interface is edited.
Refer to the section Allowed names to find out which characters are allowed and prohibited in various fields.
Name of the interface (in, out, dmz1, etc.).
A tool tip displays additional information when you scroll over the interface.
The icon shows the interface from which the administrator logged in.
The icon shows the interface being edited (open control panel).
|Port||Number of the interface’s physical port. For VLANs and modems, the port number of the parent interface appears.|
|Type||Type of interface (Bridge, Ethernet, etc.). Additional information can be displayed with the type (transfer rate, VLAN ID, etc.).|
|Status||Special statuses of an interface (disabled, not connected, monitored, etc). When the interface is enabled and connected, this column will be empty.|
|IPv4 address||IPv4 address of the interface and its mask, or DHCP address if the interface uses dynamic addresses.|
|IPv6 address||IPv6 address of the interface and its mask, or DHCP address if the interface uses dynamic addresses. This column is hidden by default if IPv6 is not enabled in the firewall’s configuration.
|MAC address||Physical interface (MAC) of the interface. This column is hidden by default.|
|System name||Name of the interface that the firewall operating system sees (em0, vlan0, etc.). This column is hidden by default.|
|Comments||Comments added during the configuration of the interface (open text field).|
Some operations can also be performed by right-clicking in the grid of interfaces. Dragging and dropping on an interface modifies its configuration (its relationships and IP address). An icon indicates whether dragging and dropping is allowed.
|Enter a filter||Searches among the firewall's interfaces.|
|Collapse all||Collapses all interfaces in the tree.|
|Expand all||Expands all interfaces in the tree.|
|Refresh displayed data||Refreshes information found in the grid of interfaces.|
|Edit||Makes it possible to edit the selected network interface or one of the modem profiles.|
|Add||Adds a new interface. The following sections explain how to add new interfaces or change the configuration of existing interfaces.|
|Delete||Deletes the selected interface. Some interfaces cannot be deleted.|
|Monitor||Enables or disables monitoring on the selected the interface. The corresponding graphs are automatically created in Monitoring > Monitoring > Interfaces.|
|Go to monitoring||Redirects to Monitoring > Monitoring > Interfaces.|
|Check usage||In the menu on the left, shows the modules in which the interface is used.|
Control panel of an interface
Interfaces can be configured in the control panel. Double-clicking on an interface displays it. The contents vary according to the type of interface selected.
