Data Transfer IP Ranges

  • Last updated on

While it is not recommended practice, some networks require you to lock down IP addresses/ranges per service. The following sections list the IP addresses used by the Barracuda Message Archiver and Cloud Archiving Service. Firewall modifications must be made for outbound traffic only. The Barracuda Message Archiver does not require you to open any inbound ports since the appliance initiates the connection to our cloud.

The IP address ranges in the following lists are subject to change without notice. If this occurs, the Barracuda Message Archiver and Cloud Archiving Service stop sending data to the cloud.

You must open outbound ports to enable communication with AWS. Refer to this AWS article for a complete list of AWS IPs or use the following list below for the specific IPs that the Barracuda Cloud Archiving Service utilizes. See also Data Transfer IP Ranges FAQ.

Note: Ensure that you do not remove any of the current IPs you have set up for outbound ACLs. 

Open Outbound Ports: 1194 (TCP/UDP), 5120-5129 (TCP/UDP), 80, 443

For On-premises Exchange Servers, also open inbound port 443.
