True or False: TOS packets apply to packets as they exit the firewall.

The statement that "TOS packets apply to packets as they exit the firewall" is false. TOS, or Type of Service, is part of the IP header and allows for the specification of the desired service quality for network packets. It is primarily used during routing decisions and signifies how a packet should be handled in terms of delay, throughput, reliability, and monetary cost.

In practical scenarios, while firewalls can inspect and potentially modify TOS settings on packets as they enter and exit, TOS primarily affects how packets are treated by routing devices and not specifically as they leave a firewall. Firewalls focus more on security policies, filtering based on rules rather than applying TOS directives consistently at exit. Therefore, the application of TOS would not inherently pertain to packets exclusively as they exit the firewall, making the statement false.
