    Configuring Internal Ports (NSM Procedure)

    The internal port, also known as the internal interface, handles all LAN requests to resources, listening for Web browsing, file browsing, authentication, and outbound mail requests.

    To configure internal port settings:

    1. In the NSM navigation tree, select Device Manager > Devices. Click the Device Tree tab, and then double-click the Secure Access device for which you want to configure internal ports.
    2. Click the Configuration tab, and select System > Network Settings > Internal Port tab. The corresponding workspace appears.
    3. Add or modify settings as specified in Table 1.
    4. Click one:
      • OK—Saves the changes.
      • Cancel—Cancels the modification.

    Table 1: Configuring Internal Port Details

    OptionFunctionYour Action
    General tab

    IP Address

    Specifies the IP address for the individual Secure Access device. By default, these boxes are populated with the settings entered during initial Secure Access device setup.

    Enter the IP address.

    Netmask

    Specifies the netmask for the individual Secure Access device. By default, these boxes are populated with the settings entered during initial Secure Access device setup.

    Enter the netmask.

    Default Gateway

    Specifies the default gateway settings for the individual Secure Access device. By default, these boxes are populated with the settings entered during initial Secure Access device setup.

    Enter the IP address for the default gateway.

    Link Speed

    Allows you to specify the speed and duplex combination you want to use for the internal port.

    Select the link speed from the drop–down list.

    ARP Ping Timeout (seconds)

    Specifies how long the Secure Access device should wait for responses to Address Resolution Protocol (ARP) requests before timing out.

    Enter the time in seconds.

    MTU (bytes)

    Specifies a maximum transmission unit for the Secure Access device’s internal interface.

    Enter the unit in bytes.

    Note: Use the default MTU setting (1500) unless you must change the setting for troubleshooting purposes.

    Routes > Destination Network/IP

    Allows you to specify the destination network/IP address.

    Enter the name/IP address for the destination network.

    Routes > Netmask

    Specifies the netmask of the static route that the Secure Access device should use when routing requests.

    Enter the netmask of the static route.

    Routes > Gateway

    Specifies the gateway of the static route that the Secure Access device should use when routing requests.

    Enter the IP address of the gateway of the static route.

    Routes > Interface

    Specifies the interface of the static route that the Secure Access device should use when routing requests.

    Enter the IP address of the interface of the static route.

    Routes > Metric

    Specifies metric for comparing multiple routes to establish precedence.

    Note: Generally, the lower the number, from 1 to 15, the higher the precedence. So, a route with a metric of 2 would be chosen over a route with a metric of 14. The metric value of zero (0) identifies the route as one that should not be used.

    Enter the metric.

    Virtual Ports tab

    Name

    Specifies a unique name for the virtual port.

    Enter the name.

    IP Address

    Specifies a unique IP alias to associate with the virtual port.

    Note: Do not use an IP address that is already associated with another virtual port.

    Enter the IP address.

    ARP Cache tab

    IP Address

    Specifies the IP address of a network device such as a router or backend application server that connects to the Secure Access device to determine the physical (MAC) address.

    Enter the IP address.

    Physical Address

    Specifies the physical address of a network device such as a router or backend application server that connects to the Secure Access device to determine the physical (MAC) address

    Enter the physical address.
