IMPORTANT
SNS 3.x versions have reached End of Maintenance since July 1st, 2024.
We recommend that you update your SNS firewalls to a version with maintenance to guarantee the protection of your infrastructure.
SNS 3.7.30 LTSB bug fixes
System
IPsec VPN
The mechanism that optimizes the distribution of the IPsec service’s encryption and decryption operations on the SNS firewall has been modified. This improves its performance when CPUs that process the packets of the IPsec service are distributed in a static manner.
To prevent packet loss in some specific cases, you can now configure how frequently ARP requests will be sent to a gateway so that ARP entries on the SNS firewall never expire.
High availability (HA) - Synchronization
Support reference 83721
Anomalies that may cause excessive memory consumption have been fixed in the mechanism that synchronizes the high availability configuration.
Number of protected hosts
Support reference 84537
An issue regarding the maximum number of protected hosts, which would arise when an SNS firewall was updated to version 3.7.28 or higher, has been fixed.
