Change in Behaviour

If a server is added with the hostname, the Barracuda Web Application Firewall will automatically create server entries for all IP addresses that resolves to the configured hostname. Deleting the first server that was added with the hostname, will now delete all the automatically created server entries. [BNWF-25536]
