Dynamic Policy-Based Routing Using Firewall Rules

A firewall is basically a defense device to control incoming and outgoing network traffic. Policies and rules are important components of a firewall that allow packets to pass through by network administration. However, administrators do not know what the destination policies and rules are, and bandwidth control and management are not efficient. A concept occurred that firewalls can transfer and learn access control lists via Border Gateway Protocol (BGP). In this paper we propose transferring firewall rules using routing protocol. This will decide and select the best path for routers over transit autonomous systems. We also propose to develop routing protocol for reducing costs, for load sharing, and to utilize and optimize problems encountered in the implementation of traffic policies on network routers.
