Migration from 8.0.1/8.0.2 to 8.0.3

  • Last updated on

This article assumes that you have already successfully upgraded to firmware version 8.0.1/8.0.2.

Before You Begin

Header Reordering for VLANs and DHCP Relay Agent


If you are using xDSL links on a VLAN interface, or if you are using the DHCP-server service or DHCP relay agent on your firewall, perform the steps below before applying the update:

  1. Go to Configuration Tree > Box > Network.
  2. On the left side, click Virtual LANs.
  3. In the list, double-click the VLAN entry where the xDSL is attached to.
  4. Enable Header Reordering.
  5. Click OK and Send Changes/Activate.
  6. Go to CONTROL > Box and click Network in the left navigation bar to expand the menu.
  7. In the left navigation bar, click Activate new network configuration.
  8. Click Soft... to trigger a network activation.

After completing these steps, install the update to 8.0.3.

Within the reboot from the firmware update, the Header Reordering setting will be applied to your VLAN interface.

If these steps are not done before the update, be aware of the following:

  • Your xDSL connection will no longer work after the update.
  • Your DHCP server will no longer work as expected for VLANs after the update.
  • Your DHCP relay agent no longer works as expected.

For more information on the setting for header reordering, see also 8.0.3 Release Notes , paragraph "Usage of DHCP on a VLAN Interface".

Barracuda Firewall Admin

After updating a system, you must also download Firewall Admin with the same version. Firewall Admin is backward-compatible. That means you can manage 7.x and 8.x F-Series Firewalls and Control Centers with Firewall Admin 8.x.

Always use the latest version of Barracuda Firewall Admin.

Read the Release Notes, especially the Known Issues section, for the firmware version that you want to update to.

For more information, see 8.0.3 Release Notes .
