![]() ![]() Dropped packets will bypass fragmentation analysis and generate an "IP fragmented packet" log entry. Under the General tab, select the Deny all incoming fragmented packets to drop any fragmented packets. ![]() You can define options for IP, TCP, UDP and ICMP packet inspection, end enable Active or Passive FTP. To edit the new configuration, select it and then click Properties.Įnter a Name and Description for the configuration.

There are three ways to define a stateful configuration on the Policies > Common Objects > Other > Firewall Stateful Configurations page: See policies and computers a stateful configuration is assigned to.When you're done with your stateful configuration, you can also learn how to Enter stateful configuration information.To create a new stateful configuration, you need to: sequence numbers, flag combinations, etc.). The TCP header is examined for correctness (e.g.The packet is examined to determine whether it belongs to an existing connection, and.A packet is passed to the stateful routine if it has been allowed through by the static firewall rule conditions,.Packets are handled by the stateful mechanism as follows: In the case of stateless protocols like UDP and ICMP, a pseudo-stateful mechanism is implemented based on historical traffic analysis. Deep Security's stateful firewall configuration mechanism analyzes each packet in the context of traffic history, correctness of TCP and IP header values, and TCP connection state transitions. ![]()
