Advancement in Firewalls Using UDP Hole Punching

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. Current solutions are only isolated or proprietary solutions because they only address certain kinds of firewall, e.g. Net filter and Cisco PIX. This paper describes a solution based on UDP hole punching.
