Before You Begin

What's New in Barracuda NextGen Firewall X-Series Version 7.2.0
This release fixes an important issue for handling entries in the redirect field of a DNAT rule.
In case the redirect field of a DNAT rule contains a mixture of IPs and one or more (nested) network object(s), you must rework all entries in the redirect field.
The redirect field of a DNAT rule must contain either only a list of discrete IPs or a single network object that contains a list of IPs. Nesting network objects is not allowed.
We highly recommend making these changes before installing this update. Otherwise, it will not be possible to change the related rulesets after the upgrade, and you will have to contact Barracuda Networks Technical Support.
