ROUTERS AND PACKET FILTERS & SERVER SECURITY
A packet-filtering router makes a permit/deny decision for each packet that it receives. The router examines each datagram to determine whether it matches one of its packet-filtering rules. The filtering rules are based on the packet header information that is made available to the IP forwarding process. This information consists of the IP source address, the IP destination address, the encapsulated protocol (TCP, UDP, ICMP, or IP Tunnel), the TCP/UDP source port, the TCP/UDP destination port, the ICMP message type, the incoming interface of the packet, and the outgoing interface of the packet. If a match is found and the rule permits the packet, the packet is forwarded according to the information in the routing table. If a match is found and the rule denies the packet, the packet is discarded. If there is no matching rule, a user-configurable default parameter determines whether the packet is forwarded or discarded.
