摘要 |
The invention relates to a method and an arrangement for connecting packet-oriented communication terminals, wherein a first communication terminal (P1) is arranged in a first network (LAN), the first network (LAN) being connected to a second network (INT) via a network address-translating unit (NAT), a second communication terminal (P2) being arranged in said second network. For this purpose, a proxy (P) is provided in the gateway (GW) for intercepting or listening to messages, in that a STUN, ICE, or TURN protocol is implemented. The concept of the invention is to implement, on a case by case basis, IP address spoofing or port number spoofing and a“RESPONSE ADDRESS”STUN field in the proxy, thereby performing the STUN or ICE protocol not on the respective communication terminals, but at a third part on another unit. A performance takes place even if the central unit is not located in the user data path between the STUN server STUN and the respective communication terminal.
