2.2. Lab Environment Details

Note

This lab guide and corresponding UDF lab blueprint are prepared for BIG-IP Next SSL Orchestrator, using a consolidated services lab architecture. All security services are consolidated into to a single Ubuntu server instance using a Docker Compose environment.

2.2.1. Network Diagram

Here is a visual representation of the virtual lab environment. The numbers inside the right edge of the SSL Orchestrator box indicate the port numbers and VLAN tags (if applicable). The colored boxes to the right of the services respresent some product examples for each respective service type.

The first interface is connected to the client-facing VLAN. The last interface is connected to the Internet-facing VLAN. One of the tagged interfaces connects to the application server VLAN. The remaining interfaces are connected to various types of security services: L2, L3, HTTP, ICAP, and passive Tap. The SSL Orchestrator management interface is not shown.

2.2.2. Virtual Lab Infrastructure Details (and Credentials)

The lab environment for this guide includes some prerequisite configuration settings that you should be aware of. These are provided to simplify this course. If you wish to use this lab guide with your own environment, please ensure that you create these objects in advance.

• Client side VLAN and subnet are pre-defined - This is the VLAN that a client connects to for traffic flows. SSL Orchestrator does not define the client-side VLAN(s) and self-IP(s).
• Server side VLAN and subnet are pre-defined - This is the VLAN that traffic egresses from the F5 BIG-IP to the web servers. SSL Orchestrator does not define the server-side VLAN(s) and self-IP(s). Consequently, the consolidated architecture will use the same interface on separate tagged VLANs to establish connectivity to the L3, HTTP, and ICAP inspection services.
• TAP service VLAN is pre-defined - This is the VLAN that traffic egresses from the F5 BIG-IP to the TAP inspection service.
• CA certificate and private key are installed - This is the CA certificate and private key that are used to re-issue (forge) remote server certificates to internal clients for outbound traffic flows.
• Server certificate and private key are installed - For the inbound (reverse proxy) traffic flow use case, SSL traffic is terminated at the F5, and re-encrypted on the way to the internal application environment. A wildcard server certificate is installed to facilitate using any name under the "f5labs.com" sub-domain.

Note

It is a security best practice to isolate security devices within the protected network enclaves provided by SSL Orchestrator. Administrators will often desire NOT to move or change existing security services. However, while possible, passing this decrypted traffic to points on an existing network architecture could create multiple points of data exposure. Usernames, passwords, credit card numbers and other personally identifiable information (PII) could be exposed to other devices on that network. It is thus recommended that security devices exist in a "private enclave" local to the BIG-IP Next instance(s). Please keep this in mind when defining the network settings for the inspection services.*

Note

Special note about BIG-IP Next and Central Manager: The F5 Central Manager (CM) employs a "fleet management" configuration paradigm for BIG-IP Next and is the "source-of-truth" for all configuration state. In most cases, objects created in CM (like iRules) are only deployed to a Next instance when they are associated to an application. With respect to SSL Orchestrator, this also applies to service chains and traffic policies. The exemption to this is inspection services. While inspection services can be saved to CM and deployed later, they are generally deployed direct to an instance on creation, irrespective of applications, as they have network attributes that are typically specific to a BIG-IP Next instance. This will be made evident in the upcoming labs.

The following tables provide device/service network configuration details. Login credentials are also provided for use as directed in the lab exercises.
