Windows Server 2012R2 Firewall Rules - Inbound and Outbound

  • Article

This article is all about allowing Standard Windows Server to communicate with the existing servers in the environment that are domain joined such as LDAP Servers for Authentication, SCOM for monitoring and SCCM for deploying updates and patches including Software deployment.

In many such cases we are left to investigate issues that are either Network Firewall related, Antivirus Software that have inbuilt Firewall policies or Windows Firewall that block communications if they are not configured with allow rules or configured with exceptions.

There are cases when Administrator have to remotely manage Servers to gather information or to deploy a script and if Windows Firewall is not setup correctly someone has to either login via Console or if it is physical server it will be a physical visit to the Datacentre to allow remote management for managing the servers.

Below set of Firewall rules can be deployed via Group Policy (TechNet Article Link )or via a script and hope this useful to setup Windows Servers with default set of policies and rules.

These rule sets are standard set of rules that allows default ports to communicate within the environment to manage and control the Server estate.

As always these are set of rules that is deployed on Test Environment as we have implemented secure Network lockdown to mimic my Production environment, so please implement this in your test/development environment prior to creating the policies in the Production environment.

Purpose of these wiki is to allow administrator to create a template that allows standard communication between the Servers in an secure lockdown environment and to be confident that Server policy is configured at the appropriate lockdown settings.
