Description

If SYN flood protection is enabled and the SYN Cookie protection threshold is exceeded, then the follow-on special additional handling for the handshake fails. The result is that the server sees an ACK for an unrecognized connection, and responds with a RST, causing the far end to shut down the connection. Note that SYN Cookie protection is enabled by default.
