SNS 3.11.23 LTSB bug fixes
Routing
Bird dynamic routing
Support reference 83650
Bird dynamic routing has been optimized to improve the speed with which routes are forwarded from the Bird dynamic routing engine to the intrusion prevention engine to prevent latency issues during the transmission of network packets.
High availability (HA)
Support reference 71538
An anomaly in the mechanism that retrieves HA information may prevent such information from being displayed in the firewall's web administration interface (Monitoring > System/High availability module). The mechanism has been optimized to reduce the frequency of this anomaly.
Intrusion prevention engine
Purging intrusion prevention engine tables
The engine has been optimized to reduce the time required to purge certain intrusion prevention engine tables and prevent the risk of packets being rejected during this operation. This issue appeared in SNS version 3.11.18.
