Port Configuration - Communication Through a Firewall

In an environment where you are using multiple Arcserve Backup servers that reside across a firewall, or there is a firewall within a Storage Area Network (SAN) fibre loop, you must configure your servers to ensure the use of fixed ports and interfaces. The configuration on your Arcserve Backup servers must match your firewall configuration so that Arcserve Backup servers can communicate with each other.

A Arcserve Backup server communicates with other Arcserve Backup servers using a set of Remote Procedure Call (RPC) services. Each service can be identified by an interface (IP address) and a port. When you share data and tape libraries between Arcserve Backup servers, the services communicate with each other using the interface and port information provided by the RPC infrastructure. RPC infrastructure, however, does not ensure specific port assignment. Therefore, you must know your RPC infrastructure and port number assignments to configure your firewall properly. To achieve static binding, additional configuration is required.

You can customize your environmental port communication settings by modifying the ports configuration file (PortsConfig.cfg) located in the CA\SharedComponents\ARCserve Backup directory.
