Firewalls separate areas of different security requirements. This major task leads to problems regarding the network connectivity and performance of various applications. In particular within distributed systems, like a Grid an unobstructed communication, which is essential for using distributed resources is not possible. Furthermore Grid applications often use multiple ports dynamically and in parallel. This raises the challenge of a dynamic configuration of firewalls. This paper shows a solution based on UDP hole punching and describes the implementation of a UNICORE transfer service using this technology to perform direct high speed file transfers.
