Setting Interface Properties Using the General Properties Screen


Use the General Properties screen to configure the following properties on an interface:

  • Name of the interface.

  • Subinterface type.

  • Zone to which the interface is bound

  • VLAN tag

  • Bundle into—Configures virtual interfaces on a Multilink Frame Relay (MLFR) for a user-to-network iterface (UNI) on available devices.

  • Encapsulation Type—Configures the following encapsulation protocols on WAN interfaces: Frame Relay, Multilink Frame Relay (MLFR), Point-to-Point Protocol (PPP), Multilink PPP (MLPPP), and Cisco High-Level Data Link Control (HDLC) on available devices.

  • Loopback interface group to which the interface belongs.

  • Redundant interface group to which the interface belongs.

  • IP address, netmask, and gateway of the interface.


    NSM does not permit you to unset the management IP aAddress. You can, however, still do this on each separate device out of band, using the CLI, the Web UI, or the supplemental CLI . See Configuring Features Unsupported in NSM Using Supplemental CLI Options Overview.

  • Mode of the interface (NAT or route)

  • Full support of IPv6 features for VLAN and loopback interfaces on ISG Series devices. See the Concepts & Examples ScreenOS Reference Guide: IPv6 Configuration.

  • DNS proxy (for details, see DNS Server Configuration Using DNS Settings).

  • PPP settings.

  • Deny routing to this interface.

  • Routing to ACVPN-dynamic.

On ADSL interfaces, you can configure ADSL options such as VPI and VCI, multiplexing mode as part of the General Properties. See ADSL Interface in ScreenOS Devices.

On wireless interfaces, you also shut down the interface by selecting the Shutdown Interface option.

Some interfaces, such as the VLAN1 or serial interface, accept service option settings as part of the General Properties for the interface. For information about service options, see Enabling Management Service Options for Interfaces.
