Abstract: Conventional Firewalls protect network entry points and are
defining for a long time the outer network security perimeter. However the
increasing need for computational power and the networking trends for increasing
connectivity and higher bandwidth threatens this architecture to become obsolete
in near future. This paper will describe the design and implementation of a
distributed Firewall using iptables, ipf and netscreen and try to resolve a real
world security problem for a large infrastructure of more than 250
servers.
