invalid ACKs in the following instances:
•
In the TCP connection SYN-ACK-received status, if the ACK
number of a received TCP packet is not exactly same as the
sequence number of the next TCP packet sending out, it is an
invalid ACK.
•
Whenever the ACK number of a received TCP packet is
greater than the sequence number of the next TCP packet
sending out, it is an invalid ACK.
The
allow
keyword allows packets with an invalid ACK.
(Default) The
drop
keyword drops packets with an invalid ACK.
Note
TCP packets with an invalid ACK are automatically
allowed for WAAS connections.
