Resolved Issues in NEN 2.7.20

Issue

Fix Description

E-140472

Exported ACL files now display All addresses for port-specific rules

When an ALL-port rule existed for a given protocol, port-specific rules for the same protocol didn't display all expected CIDR block addresses in the exported ACL file. This has been corrected: exported ACLs now include all configured address entries for each rule, ensuring customers can accurately verify and audit their enforced policy.

E-140323

Duplicate default ACLs are no longer generated on OVS bridges

In environments where an OVS bridge included multiple interfaces with attached workloads, the NEN generated the default OVS ACLs once per interface rather than once per bridge. Although these duplicate entries did not affect enforcement (because the OVS switch ignores duplicates) they could reduce readability, particularly on bridges with many interfaces. This issue is resolved. Default OVS ACLs are now generated only once per bridge.

E-137841

Secondary database service no longer fails to start after HA failback

After upgrading to PostgreSQL 16.11, the secondary database service occasionally failed to start following a NEN high‑availability (HA) failback. Restarting the affected node restored normal operation. This issue is resolved: the secondary database service now starts reliably after HA failback.

E-136789

Primary Node no longer fails to start after repeated restarts

In rare cases, repeated rapid restarts caused a primary node to fail to start. This issue is resolved: the node now starts reliably under these conditions.

E-136659

NEN Health Report no longer shows multiple entries for a node when the node's IP is changed

When the IP address of a NEN node was changed, the health report displayed multiple entries for that node, one for each IP address previously or currently associated with it. This issue is resolved: the health report now shows only a single, accurate entry per node.
