Perform Initial Configuration

By default, the firewall has an IP address of 192.168.1.1 and a username/password of admin/admin. For security reasons, you must change these settings before continuing with other firewall configuration tasks. You must perform these initial configuration tasks either from the MGT interface, even if you do not plan to use this interface for your firewall management, or using a direct serial connection to the console port on the firewall.
  1. Install your firewall and connect power to it.
    If your firewall model has dual power supplies, connect the second power supply for redundancy. Refer to the hardware reference guide for your model for details.
  2. Gather the required information from your network administrator.
    • IP address for MGT port
    • Netmask
    • Default gateway
    • DNS server address
  3. Connect your computer to the firewall.
    You can connect to the firewall in one of the following ways:
    • Connect a serial cable from your computer to the Console port and connect to the firewall using terminal emulation software (9600-8-N-1). Wait a few minutes for the boot-up sequence to complete; when the firewall is ready, the prompt changes to the name of the firewall, for example
      PA-220 login
      .
    • Connect an RJ-45 Ethernet cable from your computer to the MGT port on the firewall. From a browser, go to
      https://192.168.1.1
      .
    You may need to change the IP address on your computer to an address in the 192.168.1.0/24 network, such as 192.168.1.2, in order to access this URL.
  4. When prompted, log in to the firewall.
    You must log in using the default username and password (admin/admin). The firewall will begin to initialize.
  5. Configure the MGT interface.
    1. Select
      Device
      Setup
      Interfaces
      and edit the
      Management
      interface.
    2. Configure the address settings for the MGT interface using one of the following methods:
      • To configure static IP address settings for the MGT interface, set the
        IP Type
        to
        Static
        and enter the
        IP Address
        ,
        Netmask
        , and
        Default Gateway
        .
      • To dynamically configure the MGT interface address settings, set the
        IP Type
        to
        DHCP Client
        . To use this method, you must Configure the Management Interface as a DHCP Client.
      To prevent unauthorized access to the management interface, it is a best practice to
      Add
      the
      Permitted IP Addresses
      from which an administrator can access the MGT interface.
    3. Set the
      Speed
      to
      auto-negotiate
      .
    4. Select which management services to allow on the interface.
      Make sure
      Telnet
      and
      HTTP
      are not selected because these services use plaintext and are not as secure as the other services and could compromise administrator credentials.
    5. Click
      OK
      .
  6. Configure DNS, update server, and proxy server settings.
    You must manually configure at least one DNS server on the firewall or it will not be able to resolve hostnames; it will not use DNS server settings from another source, such as an ISP.
    1. Select
      Device
      Setup
      Services
      .
      • For multi-virtual system platforms, select
        Global
        and edit the Services section.
      • For single virtual system platforms, edit the Services section.
    2. On the
      Services
      tab, for
      DNS
      , click one of the following:
      • Servers
        —Enter the
        Primary DNS Server
        address and
        Secondary DNS Server
        address.
      • DNS Proxy Object
        —From the drop-down, select the
        DNS Proxy
        that you want to use to configure global DNS services, or click
        DNS Proxy
        to configure a new DNS proxy object.
    3. Click
      OK
      .
  7. Configure date and time (NTP) settings.
    1. Select
      Device
      Setup
      Services
      .
      • For multi-virtual system platforms, select
        Global
        and edit the Services section.
      • For single virtual system platforms, edit the Services section.
    2. On the
      NTP
      tab, to use the virtual cluster of time servers on the Internet, enter the hostname
      pool.ntp.org
      as the
      Primary NTP Server
      or enter the IP address of your primary NTP server.
    3. (
      Optional
      ) Enter a
      Secondary NTP Server
      address.
    4. (
      Optional
      ) To authenticate time updates from the NTP server(s), for
      Authentication Type
      , select one of the following for each server:
      • None
        —(Default) Disables NTP authentication.
      • Symmetric Key
        —Firewall uses symmetric key exchange (shared secrets) to authenticate time updates.
        • Key ID
          —Enter the Key ID (1-65534).
        • Algorithm
          —Select the algorithm to use in NTP authentication (
          MD5
          or
          SHA1
          ).
      • Autokey
        —Firewall uses autokey (public key cryptography) to authenticate time updates.
    5. Click
      OK
      .
  8. (
    Optional
    ) Configure general firewall settings as needed.
    1. Select
      Device
      Setup
      Management
      and edit the General Settings.
    2. Enter a
      Hostname
      for the firewall and enter your network
      Domain
      name. The domain name is just a label; it will not be used to join the domain.
    3. Enter
      Login Banner
      text that informs users who are about to log in that they require authorization to access the firewall management functions.
      As a best practice, avoid using welcoming verbiage. Additionally, you should ask your legal department to review the banner message to ensure it adequately warns that unauthorized access is prohibited.
    4. Enter the
      Latitude
      and
      Longitude
      to enable accurate placement of the firewall on the world map.
    5. Click
      OK
      .
  9. Set a secure password for the admin account.
    Be sure to use the password complexity settings to ensure a strict password.
    1. Select
      Device
      Administrators
      .
    2. Select the
      admin
      role.
    3. Enter the current default password and the new password.
    4. Click
      OK
      to save your settings.
  10. Commit your changes.
    When the configuration changes are saved, you lose connectivity to the web interface because the IP address has changed.
    Click
    Commit
    at the top right of the web interface. The firewall can take up to 90 seconds to save your changes.
  11. Connect the firewall to your network.
    1. Disconnect the firewall from your computer.
    2. Connect the MGT port to a switch port on your management network using an RJ-45 Ethernet cable. Make sure that the switch port you cable the firewall to is configured for auto-negotiation.
  12. Open an SSH management session to the firewall.
    Using a terminal emulation software, such as PuTTY, launch an SSH session to the firewall using the new IP address you assigned to it.
  13. Verify network access to external services required for firewall management, such as the Palo Alto Networks Update Server.
    You can do this in one of the following ways:
    1. Use update server connectivity test to verify network connectivity to the Palo Alto Networks Update server as shown in the following example:
      1. Select
        Device
        Troubleshooting
        , and select
        Update Server Connectivity
        from the Select Test drop-down.
      2. Execute
        the update server connectivity test.
      update-server-connectivity-test.png
    2. Use the following CLI command to retrieve information on the support entitlement for the firewall from the Palo Alto Networks update server:
      request support check
      If you have connectivity, the update server will respond with the support status for your firewall. If your firewall is not yet registered, the update server returns the following message:
      Contact Us https://www.paloaltonetworks.com/company/contact-us.html Support Home https://www.paloaltonetworks.com/support/tabs/overview.html Device not found on this update server
