Checklist: Creating Outbound Firewall Rules

This checklist includes tasks for creating outbound firewall rules in your GPOs.

Important:  By default, outbound filtering is disabled. Because all outbound network traffic is permitted, outbound rules are typically used to block traffic that is not wanted on the network. However, it is a best practice for an administrator to create outbound allow rules for those applications that are approved for use on the organization’s network. If you do this, then you have the option to set the default outbound behavior to block, preventing any network traffic that is not specifically authorized by the rules you create.
