    Performing Initial Software Configuration on the SRX240 Services Gateway Using the J-Web Interface

    This topic describes how to perform the initial configuration of your services gateway using the J-Web setup wizard that is available in Junos OS Release 11.2R2 or earlier. If your services gateway is running Release 11.2R3 or later, see Performing Initial Software Configuration on the SRX240 Services Gateway Using the Setup Wizard.

    This topic includes the following sections:

    Establishing Basic Connectivity

    To establish basic connectivity:

    1. Connect an Ethernet cable from any of the ports 0/1 through 0/15 to the Ethernet port on the management device (workstation or laptop).
    2. Connect the power cable to the device and a power source. (We recommend using a surge protector.) Note the following indications:
      • Power LED (steadily green): The device is receiving power.
      • Status LED (steadily green): The device is operating normally.

      Note: The services gateway functions as a DHCP server and will assign an IP address to the management device.

    3. Ensure that the management device acquires an IP address on the subnetwork (other than from the device.

      Note: If an IP address is not assigned to the management device, manually configure an IP address in the subnetwork. Do not assign the IP address to the management device, as this IP address is assigned to the services gateway.

    4. Access the J-Web interface:
      1. Launch a Web browser from the management device.

        Note: To access the J-Web interface, your management device requires a supported browser: either Microsoft Internet Explorer version 7.0 (or later) or Mozilla Firefox version 3.0 (or later).

      2. Enter in the Address box.
      3. Specify the default user name as root. Do not enter any value in the Password box.
      4. Press Enter. The J-Web Setup Wizard page opens.
    5. Use the wizard to configure the basic settings, such as Hostname, Domain Name, and Root Password, for your services gateway.

      The upper left area of the wizard page shows where you are in the setup process. Click a field in the wizard page to display information about that field in the lower left area of the page.

      You can also use the wizard to configure the following settings:

      • Default gateway
      • DNS servers
      • Domain search
      • VLANs
      • Interfaces

      Note: All network and management access settings are optional.

      See Table 1 and Table 2 summarize the configuration details for the initial setup.

    6. Click Commit on the Review & Commit page to apply the configuration.

      Note: After you configure the basic settings, the J-Web Setup wizard redirects you to the J-Web pages where you can continue working in the J-Web interface.

    Configuring Basic System Properties

    Table 1 and Table 2 summarize the configuration details for initial setup.

    DNS Name Servers

    Type the IP address of each server that maintains databases for resolving hostnames and IP addresses and click Add.

    Domain Search

    Type the IP address or domain name of each domain that includes the services gateway to include it in a DNS search

    Interface Groups (VLANs)


    Use buttons to add, edit, or delete VLANs

    Configure Interfaces


    Use buttons to add, edit, or delete interfaces other than VLANs.

    NTP Servers

    Add Network Time Protocol (NTP) servers that the gateway can reach to synchronize the system time.

    After you configure basic setup, the Setup wizard is no longer available, unless you reset the device to the factory default and reboot it. To make changes to the configuration, use the J-Web interface or the command-line interface (CLI).

    You can use other wizards to configure basic firewall policies, VPN settings, and NAT rules. Choose Configure > Wizards to use the available wizards. Use the J-Web interface or the CLI for more extensive configuration.
