Explanation
Packet filters forward the original packet through to the other side, while proxy firewalls create a new packet before forwarding it. The other statements are incorrect: packet filters look only at the header, not at the data of a packet. A stateful firewall is a type of packet filtering firewall that IS able to determine existing connections. Finally, proxy firewalls tend to process more slowly than packet filters, since they are looking at the data portion as well as the headers.
