SNS 3.7.5 LTSB bug fixes
System
High Availability - switch
Support references 71639 - 71681 - 72831
Whenever the active firewall in the cluster fails, high availability links that freeze would prevent the passive firewall from responding and taking over. This issue has been fixed.
High availability - SN6000 / SN6100
Support reference 72924
On clusters that handle a large number of connections (tens of thousands) involving several thousand protected hosts, the HA switch would cause connections to be lost. This issue has been resolved by using all processors to restore connections, hosts and active users.
IPsec logs (IKEv2 only or IKEv1 + IKEv2)
Support reference 73155
Some IPsec log entries (l_vpn file) would not contain the source (src) and destination (dst) fields. This anomaly has been fixed.
Intrusion prevention
IKE protocol
Support reference 73249
The SNMP protocol analyzer would wrongly block some valid IKE packets whenever SNMP packets passed through UDP port 500. This issue has been fixed.
