    • The use of Virtual Tunnel Interfaces (VTIs) disabled CoreXL through R80.10.
      Supported by default since R80.10 (through integrated MultiCore VPN). Refer tosk61701.

    • QoS is not supported with Virtual Tunnel Interface (VTI). Refer tosk34086.

    • Currently, this method is not supported for centrally managed SMB devices (1100, 1200R, 1400).Contact Check Point Supportto get a hotfix for this issue. Refer tosk111840.

    • VTIs are not compatible with:

      • 40000/60000 scalable chassis and Maestro R81 and below
      • VSX R80.40 is inferior


    Index:

    1. AWS configuration

    2. Configuration of the operating system Check Point

    3. Smart Dashboard Settings

    Teil 1: AWS-Setup

    1. In the VPC panel, click VPN Connections, then click Create VPN Connection.

      • Provide a name tag.
      • Select Virtual Private Gateway.
      • Select "New" in the customer portal:
        • Under IP Address, enter the external IP address of your Check Point Security Gateway (or the cluster's external virtual IP).
        • For "BGP ASN", keep the default value
      • Under "Routing Options" select "Static"
      • Under "Static IP Prefix" enter your local encryption domain in CIDR notation (multiple blocks can be separated with a comma).

      • In the following document we use the following notation:
        • VPC Subnets:10.10.255.0/2410.10.254.0/24
        • Local encryption domain:192.168.0.0/24 and 192.168.1.0/24
    2. After creating the VPN connection item, click Download Configuration. Select "Generic" as the provider.

    Part 2: Configuring the Check Point OS on the Security Gateway

    Monitoring:If this section is ignored, Security Gateway can sometimes lose the VPN tunnel due to AWS SLA.

    Login to your security gateway's Gaia portal.

    1. Switch to the "Network Interfaces" tab. Create a new "VPN tunnel" interface, also known as VTI:

      How to configure IPsec VPN between on-premises Check Point Security Gateway and Amazon Web Services VPC with static routes and numbered VTIs (3)

      In the downloaded configuration file, read the "IPSec Tunnel #1" section.

      • For "VPN Tunnel ID", choose any unique value (e.g. 1).
      • For Peer, provide a name to identify the VPC tunnel peer (e.g. AWS_VPC_Tun1).
      • Under VPN Tunnel Type, select Numbered
        • Under "Local address": Enter the "Internal IP address" of "Client Gateway".as specified in the configuration file. (This refers to a single gateway configuration.)
        • Under "Remote Address": Enter the "Internal IP Address" of the "Virtual Private Gateway" as specified in the configuration file.
          How to configure IPsec VPN between on-premises Check Point Security Gateway and Amazon Web Services VPC with static routes and numbered VTIs (4)
      • Repeat the above steps to create another VPN tunnel interface with the values ​​specified in the IPsec Tunnel #2 section:

        • For "VPN Tunnel ID", select a different value than the one selected above (e.g. 2).
        • Under "Partner" enter a name to identify the 2ndNorth DakotaVPC-Tunnel-Peer (als AWS_VPC_Tun2)

        *Note: The local VTI address (per cluster member) must be different from the addresses specified in the configuration file.These addresses are only meaningful locally and are used to establish the point-to-point connection between Check Point and AWS logical interfaces where next-hop VPN routes are configured for use.

        Monitoring:A two-member cluster requires four unique addresses, one for each VTI, as described above. All other settings can remain the same. A total of six VTI IP addresses would be required; the additional two are the shared addresses that will be defined later in the SmartDashboard.

    2. Navigate to the IPv4 Static Routes tab and define the VPN static routes (repeat this step for each subnet in your VPC that you want to route traffic to):

      • Click Add.
      • Specify the VPC subnet.
      • Click Add Gateway and select IP Address.
      • Enter the IP address for the first VPN tunnel remote station (as specified in the configuration file under "Next Hop") and assign it the highest priority (1).
      • Click Add Gateway and select IP Address again.
        • Enter the IP address for the second VPN tunnel point and assign it the lowest priority (2).
      • Check the Ping checkbox and click Save.

    1. Optional: Activate neutral detection.

      Monitoring:Enabling blind spot detection is optional but recommended.

      versk97746.

    2. Enable TCP MSS clamp:

      Monitoring:In most cases it is necessary to activate TCP MSS Clamping. Depending on your ISP type, the MSS value provided by AWS might work fine. However, internal testing has shown that it may be necessary to reduce Check Point's MSS capability to 1380 bytes.

    3. Definition of new network objects:

      1. In SmartConsole, create a new interoperable device:

        • For Name, specify the peer used for the first VTI (e.g. AWS_VPC_Tun1).
          The VTI name must exactly match the hostname in the SmartDashboard.
        • Under "IPv4 Address" use "External IP" from "Virtual Private Gateway" of IPSec tunnel #1.

        • Repeat this step for IPSec tunnel #2.
      2. Create an empty simple group object to act as a placeholder for the VPN domain.

    4. Looking for the VPN tunnel interfaces:

      (Monitoring:If not already done, enable Blade IPsec VPN on your gateway)

      1. Open your Security Gateway or Cluster object.

      2. Navigate to in the tree on the leftnetwork administrationbook page.

      3. Click on the top toolbarObtener interfaces>Get interfaces with no topology.

      5. Choose "Defined manually" and select the empty simple group object created earlier.

        Monitoring:If you already had a VPN domain configured, you can keep your current settings, but make sure that the hosts and networks used or served by the new VPN connection do not declare themselves in the VPN domain, especially if the VPN domain is automatically derived from ("Based on topology information").

      6. click OK.
    5. Creating the VPN community:

      1. In the upper right panelobjects, click on "VPN communities".
        create a new oneEstrellacommunity.

        Choose "Activate VPN direction matching in the VPN column".

        CliqueOK.

        How to configure IPsec VPN between on-premises Check Point Security Gateway and Amazon Web Services VPC with static routes and numbered VTIs (12)

        • Internal_clear > AWS VPN-Community
        • AWS VPN-Community > AWS VPN-Community
        • AWS VPN-Community > Internal_clear

        To create a directed match rule, right-click the VPN cell in the rule and click Edit Cell. In the VPN Match Conditions window, select Match traffic in this direction only. To add routes, click Add.

        Monitoring:Enabling direction matching rules globally in SmartConsole does not affect previously configured working VPN rules. These continue to work as expected.
