    Updating Unmanaged Units or NG Control Centers Updating Units or NG Control Centers Using SSH For speed reasons, Barracuda Networks recommends using this method of updating for all appliances in general, especially for those based on a flash drive or slower hardware.

  • Page 16: Updating Ha-Synced Units Or Ha-Synced Ng Control Centers

    For Firewall and Configuration HA synchronizing, the primary and the HA unit must both run at least firmware release versions between 4.2.11 and 5.0.3. Barracuda Networks strongly recommends to follow the procedure for updating HA systems exactly as described below in order to minimize any operational drop outs.
  • Page 17 Proceed after having assured that the HA unit is fully functional. • Unblock the (standby) servers on the HA unit by clicking Control > Servers • Log-in to the primary unit using Barracuda NG Admin. • Switch all servers from the primary to the HA unit and verify for correct operability.

  • Page 18: Updating Ng Control Center Managed Units

    Updating NG Control Center Managed Units To make use of the multi-release capabilities of Barracuda NG Control Center, all units within one cluster must run under the same software major release version. Migration of the NG CC configuration is only available for all units, servers and services of a cluster simultaneously. Step 1: Import the Update Package into the NG Control Center •...
  • Page 19 No more interaction with the unit is necessary. Wait until the update is finished. Depending on the hardware, it will need from 15 minutes on the fastest appliances up to 60 minutes on the flash appliances. Take a look into the box log file at In case of a not succeeded update please consult Box\Release\update_hotfix for a detailed log.

  • Page 20: Migrating From Phion Netfence

    If you are migrating from phion netfence 4.2.x to Barracuda NG Firewall 5.0.3 on standard hardware, you need to apply hotfix 386 before migrating from 4.2.x to 5.0.3 in order to make use of the MAC-to-eth mapping feature that will help you to keep the port labeling as it is.

  • Page 21: Updating Standard Hardware From 4.2.X To 5.0.3

    Updating Standard Hardware from 4.2.x to 5.0.3 General Due to a kernel version change between 4.2.x and 5.0.3 (Linux kernel 2.4 was changed to Linux kernel 2.6), the enumeration of NICs may on some hardware sort the ethX devices in a different order, resulting in a loss of management access.
  • Page 22 In this case you may disable MAC mapping. This will make the configuration hardware-independent, providing you with more flexibility in case hardware will be changed somewhen in the future. Further advice about updating standard hardware is available through the Barracuda Networks support. 22 Release and Migration Notes - Updating Standard Hardware from 4.2.x to 5.0.3...
