This disguise prevents the TCB of the server from staying in the SYN-RECEIVED state, thus ensuring free space in the backlog queue. The firewall/proxy will stay and wait for a period of time. If the correct ACK of the connection initiator is not detected, it will pass through the disguised TCP? The RET message causes the server to release the TCB. For legitimate connections, packet flow can continue without the influence of firewalls/proxies. This method is more attractive than the above method of disguising SYN-ACK, because the firewall/agent does not need to directly participate in the connection after the legal connection is established.Source: Uncle Kai tells a story (ID: Kaishujianggushi)The above contents are not used for commercial purposes.
