  • SYSTEM AND METHOD FOR CORRELATING IP FLOWS ACROSS NETWORK ADDRESS TRANSLATION FIREWALLS
    Publication number: 20110145391
    Abstract: Systems and methods are disclosed for correlating IP flows across a NAT firewall. Data packets are captured from a first interface using a monitor probe coupled to the first interface and are correlated into a first group of session records. For each of the first group of session records, a correlation key is created using data in one of the packets in the session record. Data packets are captured from a second interface using a monitor probe coupled to the second interface and are correlated into a second group of session records. For each of the second group of session records, a correlation key is created using data in one of the packets in the session record. The correlation key for one of the first group is compared to the correlation keys for each of the second group of session records to identify session records with matching correlation keys.
