Read this document before updating your system

If you are going to update from release version 4.2 to Barracuda NG Firewall 5.2.3 via firmware version 5.0 (no direct

update is possible!), Barracuda Networks strongly recommends to study the Barracuda NG Firewall 5.0 Migration

Instructions and also the Barracuda NG Firewall 5.2 Migration Instructions available for download at

https://login.barracudanetworks.com, as, under certain circumstances, no countermanding is possible once the

updating process was initiated.

There you will also find in-depth information on new features and changes in terminology that have been introduced

with release version 5.0.

Starting with Barracuda NG Firewall 4.2.13, OVA images for VMWare were made available. OVA images based on

minor release 4.2.13 have a bug which might lead to loss of the current network configuration when updating to

Barracuda NG Firewall minor release version 5.2.3 via major release version 5.0.

Please make sure to configure your network settings before updating virtual appliances based on 4.2.13 OVA

images using Barracuda NG Admin at least once. Also, a network activation is required.

This issue does not apply to fresh installations based on 5.2.3 OVA images.

Prior to firmware release version 5.2.3 it was for compatibility reasons possible to establish a client-to-site VPN

connection by only using any VPN client even though Exclusive Network Access (ENA) was configured on the

Barracuda NG Firewall.

With 5.2.3, it is now implicitly necessary to have the NG Personal Firewall including the packet filter SPAC installed

on the client, otherwise a connection to the VPN server will be prevented.

One time password authentication with Verisign’s Unified Authentication Tokens will only work if the new OTP

preserves State configuration parameter in the RADIUS configuration of Barracuda NG Firewall is properly set.

This parameter is only visible in Advanced mode.

The Barracuda NG Firewall may reboot after installation. If not, Barracuda Networks recommends performing a

manual reboot.
