# Post-installation steps for Forcepoint NGFW in the Layer 2 Firewall role

There are some steps to follow after you have completed the installation, installed a basic policy, and turned the Layer 2 Firewall engines online.

Note: The configuration information is stored on the Management Server. Most changes are transferred to the engines only when you install or refresh the Layer 2 Firewall Policy.

The basic administration tasks you must learn or complete next include the following:

- How to read and control the operating state of Layer 2 Firewall engines.
- Adjusting the automatic tester that monitors the operation of the Layer 2 Firewalls and the surrounding network.

After you have installed your first Layer 2 Firewall Policy, your next task is gathering information about the events detected in your networks during a “tuning period”. Once you have enough information on what kind of traffic — malicious and harmless — can be seen in your network, you can edit your policies to improve the detection accuracy and to get rid of false alarms. The most typical customization steps include:

- Creating your own policy or policy template.
- Editing the Ethernet rules, Access rules, and Inspection rules.
- Creating your own custom Situations.
