OCI - Règles d'iptables pour les travaux de sauvegarde à partir de snapshot

Sur OCI, lorsque vous déployez NetBackup Snapshot Manager sur un hôte Ubuntu, vous devez reconfigurer plusieurs règles iptables par défaut. Ces règles peuvent à leur tour entraîner des problèmes de connectivité réseau entre les services et faire échouer les travaux de sauvegarde à partir d'un snapshot, d'indexation et de restauration à partir d'une sauvegarde. Le fichier iptables se trouve à l'emplacement suivant :

etc/iptables/rules.v4

Remarque :

Les instances NetBackup Snapshot Manager configurées pour IPv6 ne sont pas prises en charge pour déploiement dans OCI.

Le contenu du fichier de règles iptables ressemble à cet exemple après avoir mis les règles présentes par défaut en commentaires :

# CLOUD_IMG: This file was created/modified by the Cloud Image build process
# iptables configuration for Oracle Cloud Infrastructure

# See the Oracle-Provided Images section in the Oracle Cloud Infrastructure
# documentation for security impact of modifying or removing these rule
