Configuring Perimeter 81 Site-To-Site with Check Point Firewall using the Check Point Smart Console

The following procedure demonstrates how to configure Perimeter 81 on a Check Point firewall using the Checkpoint Smart Console. The example values should be replaced with your actual values that can be found within your Perimeter 81 management platform. Before you start, make sure you have your gateway IP. Please follow the steps below:

Creating a gateway object at the Check Point Smart Console

 1. Open the Check Point Smart Console.

2. Go to Security Policies.

3. Add Perimeter 81 Gateway as an object as shown in the screenshot below. Please make sure you have your gateway IP (which can be found in the Network tab in your Perimeter 81 Management Platform).


 Creating a VPN Star community

1. Create a new Star Community.


2. Fill in the following information.

  • Specify an Object Name of your own choice
  • Add your Perimeter 81 gateway as Center Gateway
  • Add your external Firewall IP as Satellite Gateways

3. Go to Shared Secret.

4. Add a Shared Secret and make sure to write it down as it will also be in use configuring the tunnel at the Perimeter 81 Management Platform. Please note: Check Point recommends choosing a shared secret that contains at least 20 characters.

6. Go to Tunnel Management.

7. Set VPN Tunnel Sharing to One VPN tunnel per Gateway pair.


8. Important: The remote subnets you defined need to match exactly to the remote subnets entered within the Perimeter 81 side (if additional subnets are added, it can cause the tunnels to break from time to time).

9. Select OK. 

Additional settings at the Check Point Smart Console

1. Under Check Point firewall policy, add a rule for any to any, in and out to (this may vary if you did not set the default subnet during Perimeter 81 network creation).

2. Create a Network group with All local networks to be trusted with the VPN tunnels.
