This article refers to Barracuda Message Archiver Legacy Release firmware or higher.

Before configuring the IP address and network settings, complete Step 1 - How to Install a Barracuda Message Archiver.

Configure the IP Address and Network Settings

The Barracuda Message Archiver is assigned a default IP address of

To set a new IP address from the administrative console:

  1. Connect your keyboard and monitor directly to the Barracuda Message Archiver.
  2. At the Barracuda login prompt, enter admin for the username and for the password:
    If your appliance serial number is higher than 1311431, then the default administrator password is the numeric portion of the serial number. If your serial number is 1311431 or lower, then the default administrator password is admin. For help finding the serial number of your appliance, see Serial Number for Hardware and Virtual Appliances.
  3. For security purposes, you must change the default password of the administrator account. Set a new administrator password and click Update Password. Note that the new password cannot be admin or the serial number.

  4. The User Confirmation Requested window displays the current IP configuration of the Barracuda Message Archiver. Using your Tab key, select Change and press Enter to change the IP configuration.
  5. Enter the new IP address, netmask, and default gateway for your Barracuda Message Archiver.
  6. Enter the IP address of your primary and secondary DNS servers.
  7. Click Save to enter your changes, and then click Exit to apply the new IP address and network settings to your Barracuda Message Archiver.

Configure Your Corporate Firewall

For maximum security, place your Barracuda Message Archiver behind a corporate firewall.

If your Barracuda Message Archiver is located behind a corporate firewall, refer to the following table for the ports that must be opened on your corporate firewall to allow communication between the Barracuda Message Archiver, your email server, and the Internet:

22OutTCPRemote diagnostics and technical support services; see also Required Outbound Connections for Barracuda Networks Appliances.
25 (optional) (1) In/OutTCPEmail notifications and alerts
53OutTCP/UDPDomain Name Server (DNS)

Firmware and Energize updates (unless configured to use a proxy)

123In/OutUDPNetwork Time Protocol (NTP)
443OutTCPFirmware and Energize updates (unless configured to use a proxy)
443 (optional)InTCP

For remote access over SSL (https) to the Barracuda Message Archiver; see Enabling SSL for Administrators and Users.

8000 (default)InTCP

Web and add-in access to the Barracuda Message Archiver (2)

(1) Port 25 is the default port used for SMTP traffic. Some organizations choose to have email notifications and alerts from the Barracuda Message Archiver sent to an external email address directly or by using an external Smart Host without relaying through the corporate mail server. In these situations, the corporate firewall must be modified to allow outgoing emails from the Barracuda Message Archiver over the SMTP port.

(2) Whenever your Barracuda Message Archiver IP address is changed on the Basic > IP Configuration page, you are disconnected from the administration interface. You must log in again using the new IP address.

In general, the Barracuda Message Archiver should not accept incoming SMTP requests from systems outside your organization’s network. However, if your email server is located in a DMZ, it may be necessary to configure your corporate firewall to allow incoming traffic over the designated SMTP port from your email server to the Barracuda Message Archiver.

The port specified as the Web Interface Port must be configured on your corporate firewall to allow traffic to the Barracuda Message Archiver if you want to allow remote users to use either the web interface or the Barracuda Archive Search for Outlook.

Barracuda Networks does not recommend restricting outbound requests from the Barracuda Message Archiver by destination. Barracuda Networks appliances require outbound connections to the Barracuda cloud, AWS, Azure, and other cloud service providers in order to provide service. Outbound filtering will restrict the functionality of the Barracuda Message Archiver.
