Step 5 - Configure the Web Interface

  • Last updated on

Controlling Access to the Web Interface

The BASIC > Administration page allows you to perform the following tasks for initial setup:

  • Required: Provide email addresses in the Email Notifications section of the page so the Barracuda Email Security Gateway and Barracuda Networks can send out important alerts and informative notifications if needed.
  • Change the HTTP port used to access the web interface. IMPORTANT: For security, Barracuda Networks recommends only allowing HTTPS access – see Securing the Barracuda Email Security Gateway. To enable SSL-access only, see How to Enable SSL for Administrators and Users.
  • Change the length of time users can be logged into the web interface after a period of no activity (Session Expiration Length - default is 20 minutes).
  • Specify the IP addresses and netmask of the systems that can access the web interface. All other systems will be denied access. This is configurable in the section.

Customizing the Appearance of the Web interface

The ADVANCED > Appearance page allows you to customize the default images used on the web interface. This tab is only displayed on the Barracuda Email Security Gateway 600 and higher.

Changing the Language of the Web Interface

You can change the language of the web interface by selecting a language from the drop-down menu in the upper right corner of the page near the Log Off link. Supported languages include Chinese, Japanese, Spanish, French, and others. The language you select is only applied to your individual web interface. No other user’s web interface is affected.

Setting the Time Zone of the System

You can set the time zone of your Barracuda Email Security Gateway from the BASIC > Administration page. The current time on the system is automatically updated via Network Time Protocol (NTP). When the Barracuda Email Security Gateway resides behind a firewall, NTP requires port 123 to be opened for outbound UDP traffic. You can specify one or more NTP servers to use on the ADVANCED > Advanced Networking page. Each server will be tried in order until one successfully connects. The default server is

It is important that the time zone is set correctly because this information is used in all logs and reports.
Note: The Barracuda Email Security Gateway automatically reboots when you change the time zone.
