AWS Hub East-West

Valtix Gateway is deployed in a Shared Service VPC to protect the applications in the Spoke VPCs. The Gateway acts as a reverse proxy. The users on the internet access the application via the Valtix Gateway. Configure the backend destination (the original application) as a proxy target on the Valtix Gateway. The proxy enables Valtix to decrypt TLS traffic and perform deep packet inspection. The proxied traffic to the backend/target can be sent as plain text HTTP, HTTPS, TCP or TLS.

To add a Gateway:

  1. Navigate to Manage -> Gateways -> Gateways
  2. Click Add Gateway
  3. Select the account you previously created
  4. Click Next

    Parameter Description

    Gateway Type Auto Scaling. (Look at the implementation guide for single instance Gateway and the use case for that)
    Minimum Instances Select the minimum number of instances that you plan to deploy
    Maximum Instances Select the maximum number instances that you plan to deploy. This is the maximum number that is used for auto-scaling in each availability zone
    HealthCheck Port Default is 65534
    Packet Capture (optional) Packet capture profile for threat pcaps
    Diagnostics (optional) Diagnostics profile for debugging
    Log (optional) Log profile to forward to Splunk or syslog
  5. Click Next

  6. Provide the following parameters

    Parameter Description

    Security Choose East-West
    Gateway Image Image to be deployed
    Policy Ruleset Select the policy ruleset to associate with this Gateway. If you don't have any policy ruleset you can create a new by choosing Create New
    Region Select the region this Gateway will be deployed into
    VPC Select the Service VPC in which the Valtix Gateway is deployed
    Transit Gateway Select a transit Gateway or create a new one. You can reuse the same Transit Gateway for all kinds of security types
    Key Pair Select the key pair to associate with this Gateway
    IAM Role for Gateway Select the IAM role to associate with this Gateway
    Mgmt. Security Group Automatically selected
    Datapath Security Group Automatically selected

    Availability Zones and subnets are automatically selected from the Service VPC.

  8. Click Finish. The Gateway deployment starts and takes approximately 5-7 minutes for the Gateway to become ACTIVE

Tech Notes

  • On your AWS console, view the EC2 instances page and check the Gateway instances created. The instances have a Name tag that begins with valtix.

  • Check the AWS Console Load Balancers section and note that an internal Network Load Balancer has been created. It does not yet have any listeners or target groups. The listeners and target groups (targeting the EC2 Valtix Gateway instances) are created when you add a service with the listener port and backend application.

  • Review the AWS Transit Gateway and note that a new TGW (if create was selected) has been created. An Attachment to the Service VPC is created, a TGW route table is also created and associated with the Attachment.
