When the client SYN packet arrives at the filter gateway, the SYN agent does not forward the SYN packet, but actively replies the SYN/ACK packet to the client in the name of the server. If the client's ACK packet is received, it indicates that this is normal access. At this time, the firewall sends the ACK packet to the server and completes three handshakes. The SYN agent actually replaces the server to deal with SYN attacks. At this time, the filter gateway itself is required to have strong ability to prevent SYN attacks.
