Abstract

The present invention relates to a method, computer program products, and a computer readable medium for communication between a first computer unit (11) and a second computer unit (2) via a network (A), wherein said communication takes place via a third computer unit(3). A firewall (21) is established between the second computer unit (2) and the third computer unit (3), and all communication between these computer units (2, 3) takes place through said firewall(21) via ports (41, 42, 43, 44) that have been initiated or opened (51, 52, 53, 54) by the second computer unit (2).
