Configuring Firewalls to Optimize Communication Ports Used by CA ARCserve Backup Components The following sections provide information about ports used by CA ARCserve Backup components, primarily for Windows configurations. This section contains the following topics: External Ports Used for Communication (see page 230) Ports Used by the CA ARCserve Backup Base Product (see page 231) Ports Used by CA ARCserve Backup Common Components (see page 239) Ports Used by CA ARCserve Backup Agents and Options (see page 240) How to Allow Agents and Database Agents to Communicate through a Firewall (see page 245) CA ARCserve Backup Dashboard for Windows Firewall Communication Configuration (see page 247) Additional Resources - Firewall Ports Specifications (see page 248) External Ports Used for Communication CA ARCserve Backup uses the following external ports for communication: Port 135 This is owned by Microsoft endpoint-mapper (Locator) Service and is not configurable. All CA ARCserve Backup MSRPC services register their current ports with this service. All CA ARCserve Backup clients (for example, the Manager) contact this service to enumerate the actual port used by the CA ARCserve Backup service and then contact the service directly. Port 139/445 This is owned by Microsoft and is not a configurable port. CA ARCserve Backup services use MSRPC over the Named Pipes transport. Microsoft requires this port to be open for all communication using MSRPC over Named pipes. Be aware of the following: ■ Port 139 is used only when the CA ARCserve Backup services are installed on Windows NT. ■ Port 445 is used only when the CA ARCserve Backup services are installed on Windows XP, Windows Server 2003, and Windows Server 2008. 230 Implementation Guide
