A stateful inspection firewall keeps track of the state of network connections by inspecting the packets at the transport layer. It does this by maintaining a record of the packets that have been sent and received, and using this information to determine if packets are part of an established connection or not.

If packets are out of order or damaged, the firewall may not be able to fully inspect them, but it can still use the information it has gathered about the connection to make some determinations. For example, if a firewall sees a packet that is out of order and does not match the established state of the connection, it may assume that the packet is part of a new or malicious connection and block it.

Similarly, if a packet is damaged and cannot be fully inspected, the firewall may still be able to determine some information about the packet based on its header and other metadata. For example, the firewall may be able to determine the source and destination IP addresses and ports, which can be used to make decisions about whether to allow or block the traffic.

Overall, while packet reordering and damage can make it more difficult for a stateful inspection firewall to fully inspect traffic, the firewall can still use the information it has gathered about the connection to make some determinations about the traffic and take appropriate actions
