TCP: C2S Old Packet Old Timestamp in ESTABLISHED
This protocol anomaly triggers when it detects a packet with a time-stamp that is older than a previously recorded time-stamp (as specified by RFC1323) earlier. Because these ambiguous packets can be interpreted by the receiving host in different, unpredictable ways, it is recommended to drop them.
