How to Configure VXLAN on Fortigate

Hello everyone, in this video I will show how can you extend VLANs over IP. In FortiGate by using vxlan you can do this.

How to Configure VXLAN on Fortigate

1. Access the FortiGate GUI:

  • Open a web browser and enter the IP address of your FortiGate firewall to access the graphical user interface (GUI).
  • Log in with administrator credentials.

2. Create VXLAN Interface:

  • Navigate to Network > Interfaces.
  • Click Create New and select VXLAN.
  • Fill in the following details for the VXLAN interface:
    • Name: A descriptive name for the VXLAN interface (e.g., VXLAN1).
    • Alias: An optional alias for identification purposes.
    • VLAN ID (Optional): If you want to associate the VXLAN interface with a specific VLAN, provide the VLAN ID.
    • VXLAN ID (VNI): Specify a unique VXLAN ID. This is critical, as it is used to identify the VXLAN segment. Ensure that VNIs match across devices in your VXLAN network.
    • VXLAN Port: Specify the UDP port for VXLAN traffic (default is 4789).
  • Click OK to create the VXLAN interface.

3. Configure VXLAN Settings:

  • Under Network > VXLAN, select the VXLAN interface you just created.
  • Configure the following VXLAN settings:
    • Local IP Address: Enter the IP address associated with the FortiGate’s VXLAN interface. This IP should be on the same subnet as the VXLAN endpoints.
    • Multicast Address (Optional): If you intend to use multicast for VXLAN traffic, specify a multicast IP address. Ensure that both ends of the VXLAN have the same multicast settings.
    • Remote IP Address (Peer): Enter the IP address of the remote FortiGate firewall or VXLAN endpoint that you want to connect to.
  • Click OK to save the VXLAN settings.

4. Create VXLAN Overlay Network:

  • Go to Policy & Objects > Objects.
  • Click Create New and select Virtual Network.
  • Fill in the VXLAN overlay network details:
    • Name: A descriptive name for the VXLAN overlay network.
    • Interface: Select the VXLAN interface you created in step 2.
    • VXLAN ID (VNI): Set the same VNI as you did in the VXLAN interface configuration.
  • Click OK to create the VXLAN overlay network object.

5. Create Firewall Policies:

  • Under Policy & Objects > IPv4 Policy, create firewall policies to allow traffic between VXLAN overlay networks or between VXLAN networks and the physical network.
  • In the policy settings:
    • Define the source and destination addresses using the VXLAN overlay network objects you created.
    • Specify the desired action (e.g., allow).
    • Set any required security profiles, such as antivirus or intrusion prevention.
  • Click OK to create the firewall policy.

6. Routing (if needed):

  • If routing between VXLAN overlay networks or between VXLAN and physical networks is necessary, configure routing on the FortiGate firewall.

7. Security Profiles (if needed):

  • Apply security profiles to the firewall policies to enhance security for VXLAN traffic. These profiles can include antivirus scanning, intrusion prevention, and application control.

8. Monitor and Troubleshoot:

  • Use the FortiGate GUI or CLI to monitor the VXLAN interface’s status and traffic.
  • Check logs for any issues or errors related to VXLAN.
  • Verify that routes are correctly configured, especially if you have multiple VXLAN segments.

9. Repeat on Remote FortiGate (if applicable):

  • If you have multiple FortiGate firewalls participating in the VXLAN network, repeat the configuration steps on the remote FortiGate(s), ensuring that VXLAN settings match on both ends.

10. Test and Verify:

  • Test connectivity between devices on the VXLAN overlay networks to ensure that traffic is correctly routed and policies are applied.

Always consult the Fortinet documentation for your specific FortiGate model and firmware version, as there may be slight variations in the user interface and configuration options.

Reset Password for HP storage

Hello everyone. In this video I will show how you can reset your HP storage password. With this method, you can reset any type of HP storage password.

Reset Password for HP storage

Note: Before proceeding, ensure you have the necessary permissions and authority to reset passwords, as this action can have security implications.

  1. Access the Management Interface:
    • Connect a computer to the same network as the HP storage system.
    • Open a web browser and enter the IP address of the storage system. This IP address can usually be found on a label on the front or back of the storage device.
    • Log in to the management interface using the current administrator username and password. If you’ve forgotten the password, proceed with the password reset.
  2. Locate the Password Reset Option:
    • Explore the management interface menus and navigation options to find the password reset feature. Common locations include:
      • System Settings: Look for options related to “User Management,” “Security,” or “Authentication.”
      • User Management: Navigate to the user management section where you can edit user profiles.
  3. Select User Account:
    • In the user management section, locate your user account or the account for which you want to reset the password.
  4. Initiate Password Reset:
    • Click on the user account, and you should see an option to reset the password. This might be labeled as “Change Password,” “Reset Password,” or something similar.
  5. Identity Verification:
    • You may be prompted to verify your identity. This can be done by providing information such as your username, email address, or answering security questions.
  6. Reset Password:
    • Once your identity is verified, you can reset the password. You’ll typically need to enter a new password and confirm it. Make sure to create a strong and secure password following any password policy requirements.
  7. Confirmation:
    • After successfully resetting the password, you should receive a confirmation message. It may include information about the updated password and any changes made to your account.
  8. Log In with New Password:
    • Use the newly reset password to log in to the management interface. Ensure that the new credentials work as expected.
  9. Update Password Policy (if necessary):
    • It’s advisable to review and update the password policy settings to align them with your organization’s security requirements. This might include setting password expiration periods and complexity requirements.
  10. Test Access:
    • Confirm that you can access and manage the HP storage system using the new password.
  11. Document the Changes:
    • It’s important to maintain a record of password changes for audit and security purposes. Document the date and reason for the password reset.
  12. Securely Store the New Password:
    • Store the new password securely, and ensure that only authorized personnel have access to it.

If you encounter any difficulties during the password reset process or have concerns about security, consider contacting HP support or your IT department for assistance. Always prioritize security when managing passwords for your storage systems.
