ABSTRACT:
The invention concerns handling in a firewall data communication protocols comprising at least one parent connection and at least one related connection, wherein at least one attribute of the related connection is negotiated within the parent connection. Whether to allow a related connection is decided on the basis of information about the related connection as well as information about the parent connection. The method of the invention comprises allowing a parent connection, storing information about the parent connection, monitoring contents of the parent connection, detecting within the parent connection negotiation of at least one attribute of a related connection, and using said at least one negotiated attribute of the related connection and said information about the parent connection for deciding, whether said related connection is allowable.
