20. A firewall arrangement for communication data transmitted between terminal devices, comprising:
-
a firewall device disposed between a first communication network and a second communication network;
a first terminal device disposed in the first communication network;
a second terminal device disposed in the second communication network;
a first network interworking device disposed in the first communication network; and
a second network interworking device with a known address for performing an authentication on the basis of authentication data transmitted by the first terminal device and for sending a selected further address of the second terminal device to the firewall device for activating the firewall device for the signaling data to be sent from the first terminal device to the second terminal device. - View Dependent Claims (21)
