How does a packet filter process IP header criteria?
What will be an ideal response?
A stateless filter looks at each packet's header individually. It compares the header data against its rule base and forwards each packet as a rule is found to match the specifics of that packet. For instance, if the filter has a rule stating that all connections from outside the network are to be blocked and it receives a request from an external host, it drops the packet(s) associated with that request.
