Interfaces

The Interfaces page configures the network interfaces or the server.

Interfaces Grid

The Interfaces tab shows the current interfaces and the current status and some configuration information.

The are several columns along the top of the grid that show the current interface status and configuration. Some are hidden by default.

Columns

Column Description
Id The Id is a unique integer primary key of the interface. All configuration of interfaces will refer to Id.
Name This is a name/description of the interface. It is recommended to choose names representative of their purpose.
Connected This shows the current "connected" state of the device currently mapped to this interface. This may not display correctly for all network interface cards.
Device This shows the current network device (physical NIC card or wireless card) mapped to this interface.
Config This shows the current type of configuration for this interface. ADDRESSED, BRIDGED, or DISABLED.
Current Address This shows the current address if there is one of the interface.
is WAN This shows true if the interface is configured as a WAN, false otherwise.
Edit This column shows an edit button to edit the configuration of this interface.
Delete This column shows an delete button on VLAN Tagged Interfaces to delete the interface. Physical interfaces cannot be deleted, unless their their physical devices have been removed from the system.

There are also several additional options on this page:

  • Remap Interfaces
    • This utility can be used to change the mapping between physical devices and the corresponding interface configurations. This is useful if you want to use certain physical devices for certain purposes.
  • Refresh Device Status
    • This refreshes the "Connected" column in the interfaces grid. To verify your interface mapping plug/unplug one network card at a time and hit Refresh Device Status to verify that the expected interface changes the Connected status.
  • Add VLAN Tagged Interface

Interface Configuration

Clicking the edit button on an interface will open the interface configuration settings for that interface.

An interface can be configured in many ways. Some settings and configuration options are only relevant and/or available in certain configurations. As such, based on an interface's configuration certain options may appear and disappear. For example, when checking 'is WAN' the options available to WAN interfaces will appear. After unchecking 'is WAN' the WAN options will disappear and the options for non-WAN interfaces will appear. Because of this it is suggested to configure your interface from the top of the page downward.

The table below shows the various configuration options and their meanings.


Interface Options

Option Description
Interface Name This is a name/description of the interface. It is recommended to choose names representative of their purpose.
is VLAN (802.1q) Interface This is true if this a tagged VLAN interface. Otherwise this is not shown
Parent Interface This is the parent interface for this tagged VLAN interface. This is only shown for VLAN interfaces.
802.1q Tag This is the VLAN tag for this interface. This is only shown for VLAN interfaces.
Is Wireless Interface This is available if the interface is detected as a wireless (wlan) interface. Otherwise this is not shown.
Config Type This is the basic configuration type of this interfaces. Addressed means this interface has its own address and configuration. Bridged means this interface is bridged to another interface. Disabled means this interface is entirely disabled.
is WAN Interface This should be checked if this is a WAN (Wide Area Network) interface. This means it is connected to your ISP or an internet connection. This should be unchecked if this interface is connected to a private/local network.


Wireless Configuration - This section configures the wireless settings for wireless interfaces. This is only shown for wireless interfaces.

Option Description
SSID The broadcasted Service Set Identifier (SSID) for the wireless network.
Mode AP (Access Point) or Client.
Visibility Select whether to advertise or hide the SSID.
Encryption Encryption method used for the wireless signal. WPA2 is recommended.
Password When encryption is enabled, a password will be required to access the network.
Regulatory Country Choose the country in which this NG Firewall is based. This is required to comply with regulations around Wi-Fi bands & frequencies.
Channel Choose from the available channels available and 2.4GHz or 5GHz frequencies. The options available here are dependent on your wireless card. WARNING: Many chips/drivers do not correctly implement "Automatic" (ACS or Automatic Channel Survey) so it may not work depending on your card. NOTICE: Automatic channel selection has been removed from modern builds due to lack of support and usability issues.


IPv4 Options - This section configures the IPv4 (Internet Protocol v4) settings of this interface.

Option Description
Config Type This is the IPv4 configuration type. Static means this interface has a static IPv4 address. Auto (DHCP) means this interface will use DHCP to automatically acquire an address.

Netmask Override If set, this netmask will be used instead of the one in the offered DHCP lease. It is only shown if Config Type is Auto (DHCP)
Gateway Override If set, this gateway will be used instead of the one in the offered DHCP lease. It is only shown if Config Type is Auto (DHCP)
Primary DNS Override If set, this will be used instead of the one in the offered DHCP lease. It is only shown if Config Type is Auto (DHCP)
Secondary DNS Override If set, this will be used instead of the one in the offered DHCP lease. It is only shown if Config Type is Auto (DHCP)
Username This is the PPPoE username. It is only shown in Config Type PPPoE
Password This is the PPPoE password. It is only shown in Config Type PPPoE
Use Peer DNS If checked the server will use the DNS provided by the PPPoE server for DNS resolution. It is only shown in Config Type PPPoE
Primary DNS The primary DNS to be used for DNS resolution. It is only shown in Config Type PPPoE and Use Peer DNS is unchecked.
Secondary DNS The secondary DNS to be used for DNS resolution. It is only shown in Config Type PPPoE and Use Peer DNS is unchecked.
