ABSTRACT:
The present invention provides systems and methods for performing storage operations through a firewall. Methods are provided that include, in a networked computer system, identifying, based on configuration data, whether each of a set of network elements is within a trusted network or not within the trusted network. Traffic between elements within the trusted network and elements not within the trusted network must pass through a firewall. The methods also include, prior to performing a storage operation through the firewall, allocating a specific set of ports, in accordance with at least one security parameter, for use in performing the storage operation. Methods are also provided which include monitoring traffic through the specific ports, and, if traffic is determined to be inactive through a first port of the specific ports, sending a packet through the first port.
