I need question 2 answered

1. A SYN-ACK amplifier is a TCP server listening on a given port, that re-send its SYNACK handshake message when it does not receive an ACK (or RST) response. For simplicity, assume SYN-ACK amplifiers retransmit after one second, and repeats this up to 10 times if necessary. Illustrate the use of a SYN-ACK amplifier for a bandwidth DoS attack (you can use Figure 1 as a template). Note: Assume that the victim 1 Figure 1: A template sequence diagram. is 'behind' a RST-dropping router (FW), i.e., a router which drops all RST packets. 2. Explain why the attack requires the victim to be 'behind' a RST dropping router (FW)
