Configuring Advanced Settings for a WAN Interface

To configure advanced settings for a WAN interface

  1. In the Edit Interface dialog, click Advanced.

  2. For Link Speed, Auto Negotiate is selected by default, which causes the connected devices to automatically negotiate the speed and duplex mode of the Ethernet connection. If you want to specify the forced Ethernet speed and duplex, select one of the following options from the Link Speed menu:

    For 1 Gbps interfaces For 10 Gbps interfaces
    1 Gbps - Full Duplex 10 Gbps - Full Duplex
    100 Mbps - Full Duplex
    100 Mbps - Half Duplex
    10 Mbps - Full Duplex
    10 Mbps - Half Duplex

    If you select a specific Ethernet speed and duplex, you must force the connection speed and duplex from the Ethernet card to the firewall as well.

  3. You can choose to override the Use Default MAC Address for the Interface by selecting Override Default MAC Address and entering the MAC address in the field.
  4. Select Shutdown Port to temporarily take this interface off line for maintenance or other reasons. If connected, the link goes down. Clear the checkbox to activate the interface and allow the link to come back up.
  5. For the AppFlow feature, select Enable flow reporting to allow flow reporting on flows created for this interface.
  6. Select Enable Multicast Support to allow multicast reception on this interface.
  7. Select Enable 802.1p tagging to tag information passing through this interface with 802.1p priority information for Quality of Service (QoS) management. Packets sent through this interface are tagged with VLAN id=0 and carry 802.1p priority information. In order to make use of this priority information, devices connected to this interface should support priority frames. QoS management is controlled by access rules on OBJECT | Profile Objects > QoS Marking. For information on QoS and bandwidth management, see SonicOSX System Administration Guide.
  8. Optionally select Link Aggregation or Port Redundancy from the Redundant /Aggregate Ports drop-down list. For more information see Configuring Link Aggregation and Port Redundancy.
  9. Interface MTU - Specifies the largest packet size that the interface can forward without fragmenting the packet. Identify the size of the packets that the port receives and transmits:
    Standard packets (default)1500
    Jumbo frame packets9000
    • Fragment non-VPN outbound packets larger than this Interface’s MTU - Specifies all non-VPN outbound packets larger than this Interface’s MTU be fragmented. Specifying the fragmenting of VPN outbound packets is set in Network| IPSec VPN | Policies/Settings; for more information about VPN traffic, see SonicOSX Network Administration Guide.
    • Ignore Don’t Fragment (DF) Bit - Overrides DF bits in packets.
    • Suppress ICMP Fragmentation Needed message generation - blocks notification that this interface can receive fragmented packets.
  10. If using DHCP, the following options are displayed:
    • Select Initiate renewals with a Discover when using DHCP if the server might change.
    • Select Use an interval of _ seconds between DHCP Discovers during lease acquisition and adjust the number of seconds for the interval if the DHCP server might not respond immediately.
  11. Optionally enable Bandwidth Management for this interface. For more information about Bandwidth Management, see Enabling Bandwidth Management on an Interface.
