SNS 3.11.18 LTSB bug fixes
System
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.
Hosts with dynamic IP address resolution used in sub-groups
Support references 84202 - 81951
Whenever a host was:
- Configured with dynamic IP address resolution,
- Placed in a sub-group that is in turn used in a configuration module on the SNS firewall (filter rules, permissions to access the web administration interface, etc.).
Changes to this host’s IP address would be ignored in the configuration module in question. This issue has been fixed.
TNS protocol - Oracle
Support reference 84341
Analyses of TNS - Oracle client-server communications that undergo packet fragmentation and address translation (NAT) no longer desynchronize traffic due to packets being rewritten.
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 3.11, has been fixed.
