Abstract

A first computer (12) transmits data to a second computer (21) in accordance with a first protocol. The second computer (21) receives the data and transmits them to a third computer (11), which is within a secure network, using a second protocol that is different from the first protocol. The data is transmitted to the third computer over a connection originated from within the secure network, thereby allowing the data to pass through network security devices such as firewalls (15).
