Created on  | Last modified on 

Description

When implementing a Multi-Node environment, or adding a new server component to an existing environment, it can be easy to forget to open certain ports in the firewalls to allow network traffic to flow correctly between servers 

 UPDATE April-2021 : The Online Help "Security Best Practices" document ( https://online-help.sageerpx3.com/erp/12/staticpost/security-best-practices/ ) has been updated and superceeds this article, as it now gives specific guidence for the external access. 

 This article aims to give a quick guide to the network traffic with sample port numbers, which will hopefully act as a aide-memoire when adding your firewall rules

CAUTION: This solution requires advanced knowledge of your network. Contact your system administrator for assistance. Modifying Windows security incorrectly can severely affect system operations. Sage is not responsible for operation issues caused by incorrectly modifying your Windows security. Always create a backup of your data before proceeding with advanced solutions. 

The following diagram shows a sample multi-node setup. The boxes representing the servers list the Sage X3 required components installed on that server and the ports being used. The lines between the boxes show the flow of traffic which would need to be allowed between servers.

Note: you should configure firewall rules to restrict access by specific IP address for the inter-server traffic
