# Integrating Engine/VPN role with IPS and Layer 2 Engines

You can use Forcepoint Network Security Platform in the Engine/VPN role, IPS, and Layer 2 Engine roles together for traffic inspection.

IP address Block Listing is a shared feature for Security Engine in the Engine/VPN role, IPS, and Layer 2 Engine roles. Block Listing allows blocking harmful traffic not just at the component that detects it, but also on other engines on the connection path.

Instead of using Security Engines in the IPS or Layer 2 Engine role, you can also use layer 2 interfaces on Security Engines in the Engine/VPN role for traffic inspection.
