Administrative Settings

This section covers the basic administrative settings for your Barracuda Load Balancer.

Controlling Access to the Administration Interface

The
Basic > Administration
• Change the password of the administration account.
• Specify the IP addresses or subnet mask of the systems that can access the Web interface. All
other systems will be denied access. This is configurable in the Administrator IP/Range
section.
• Change the port used to access the Web administration interface.
• Change the length of time of inactivity allowed until the administrator is logged out of the Web
interface.

Customizing the Appearance of the Web Interface

The
Advanced > Appearance
interface. This tab is only displayed on the Barracuda Load Balancer model 440 and above.

Setting the Time Zone of the System

The
Basic > Administration
The current time on the system is automatically updated via Network Time Protocol (NTP). When the
Barracuda Load Balancer resides behind a firewall, NTP requires port 123 to be opened for outbound
UDP traffic.
It is important that the time zone is set correctly because this information is used to coordinate traffic
distribution and in all logs and reports.
Note: The Barracuda Load Balancer automatically reboots when you change the timezone.

Enabling SSL for Administration

The
Advanced > Secure Admin
interface for your Barracuda Load Balancer. You can use this page to specify whether to require
HTTPS for secure administration. If you choose to use HTTPS, you can specify the certificate to be
used.
SSL not only ensures that your passwords are encrypted, but also ensures that the rest of the data
transmitted to and received from the Web administration interface is encrypted as well. For users who
want to allow only secured connections, set up SSL.
