r4600 Tenant CPU Assignment
The r4600 has 12 CPUs (by default) available for a max of 2 tenants. My initial thought was to assign 6 CPUs to each but that is not an option. 4, 8, or 12 are the only options. Question: Are these options of 4, 8, or 12 CPUs arbitrary or do they have to do with the Atom chip architecture? It seems like a waste. I can either do 4 CPUs each wasting 4 or do a 4 CPU tenant and an 8 CPU tenant. The only other option would be to purchase the license for the additional 4 CPUs to make each tenant 8 CPU.

Clustering among VCMPs and Tenants ( rSeries )
Hello guys, we are approaching a migration from a vCMP cluster to a Tenant ( on r5600 ) cluster . VLAN/Networks betweeen old and new nodes will be the same and the migration will be VIPs based ( not every vs at once ). I was wondering if it is possible to add Tenant nodes to the already vCMP device group so that we can continue to have a synced configuration during the migration . Has anyone ever configured a mixed device group with vCMPs and Tenants running on r-series ? thank you in advance
F5OS missing interfaces in tenant
Hello, I'm totally new to F5OS, I'm configuring a rSeries 2600 (1.5.1-12283) and deploying a tenant (BIG-IP 15.1.5.1 Build 0.0.14 Point Release 1). All seemed to work perfectly fine both in the host and the tenant deployments, but looking at the interfaces section on the tenant the list is totally empty! And in VLAN properties the "interface" section is missing. I assigned VLAN's to interfaces in the Network Settings at F5OS level - would it be by design that the interfaces are no longer showed in the tenant ? I tried to find info in the doc with no results... Any info/help would be more than welcome :-) Thanks & have a good day, Gerald
Office 365 Tenant Restrictions
Introduction This use case allows you to access Company Office 365 resources while blocking access to personal/non-company Office 365 resources. In this scenario, SSL Orchestrator injects Microsoft "Tenant-Restriction" HTTP headers into outbound HTTP flows. The concept of Tenant Restrictions provides a mechanism to allow or deny access to Office 365 resources based on organizational requirements. For example, you may wish to allow access to Company Office 365 Outlook mail but deny access to the same resource when using a personal account. Detailed information from Microsoft on Tenant Restrictions is available here[1]. In order to configure Tenant Restrictions, you need your company's ‘Restrict-Access-To-Tenants’ and ‘Restrict-Access-Context’ values. You can obtain these from the Microsoft Azure portal by signing in as the Administrator here[2]. After logging in select View under Azure Active Directory. Your Tenant Domain and Tenant ID will be shown like in the image below. Restrict-Access-To-Tenants – a value of permitted tenant lists, which is a comma-separated list of tenant domains that users are allowed to access. Any domain that is registered with a tenant can be used to identify the tenant in this list. For example, to permit access to both Contoso and Fabrikam tenants, the name/value pair would look like this: Restrict-Access-To-Tenants: contoso.onmicrosoft.com,fabrikam.onmicrosoft.com Restrict-Access-Context - a value of a single directory ID, declaring which tenant is setting the Tenant Restrictions. For example, to declare Contoso as the tenant that sets the Tenant Restrictions policy, the name/value pair would look like this: Restrict-Access-Context: 456ff232-35l2-5h23-b3b3-3236w0826f3d. This article assumes you have a working SSL Orchestrator Deployment configured and wish to add Office 365 Outlook Tenant Restrictions. Steps 1. Create a Custom URL category – this will hold the Microsoft login URLs that require the Tenant Restrictions headers. 2. Create the ICAP service - the ICAP service is a flexible, transactional service type. We’ll use this as the framework for injecting Tenant Restrictions headers. 3. Create a security policy - the SSL Orchestrator security policy is the engine that maps traffic flows to actions (allow/block, decrypt/bypass, service chain). We’ll create a Security Policy that looks for the Microsoft login URLs (from the custom category) and assigns this traffic to the modified ICAP service. 4. Create an iRule - this iRule actually does the work of injecting the HTTP headers and will be applied to the modified ICAP service. 5. Test the Tenant Restrictions Step #1 Create a custom URL category From the SSL Orchestrator Configuration screen select Policies > URL Categories Click Create Give it a Name, Office365 in this example Uncheck the box for Global Pattern Match. Add all of the following: https://login.microsoftonline.com/ https://login.microsoftonline.com https://login.microsoft.com/ https://login.microsoft.com https://login.windows.net/ https://login.windows.net Click Finished when done Step #2 Create an ICAP Service in existing Topology From the SSL Orchestrator Configuration screen select Services then click Add Note: if you do not have a Topology created you can still use this guide and create the ICAP Service at the time the Topology is created. The order of events will be slightly different. Scroll to the bottom, select Generic ICAP Service and click Add Give the ICAP Service a name, Office365_Tenant in this example. For ICAP Devices click Add. Enter an IP Address, 198.19.97.1 in this example and click Done. Note: the IP address you use does not have to be the one above. It’s just a local, non-routable address used as a placeholder in the service definition. This IP address will not be used. IP addresses 198.19.97.0 to 198.19.97.255 are owned by network benchmark tests and located in private networks. Scroll to the bottom and click Save & Next. On the next screen click Add to create a new Service Chain Give it a name, O365_Service_Chain in this example. Select your existing Services and click the right arrow to move them to Selected. Add the ICAP Service last. Note: It’s important to know why you’re creating a new Service Chain. The custom category will be applied to a Security Policy rule to match on requests for specific Office 365 login URLs. If that condition matches, the traffic must be intercepted (decrypted), and sent to a Service Chain with the Office 365 Service. Multiple Services can be in this Service Chain. However, if you put the Office 365 Service in any other service chain, the tenant restrictions headers will be sent to other sites incorrectly. It should look like the following. Click Save. Note: the new Service Chain should look like your previous Service Chain with the addition of the Office365 ICAP Service at the end. It is important to do it this way to ensure Login activity to Office 365 is still inspected. Click Save & Next Click Deploy You should receive a Success message. Step #3 Create a security policy From the SSL Orchestrator Configuration screen select Security Policies then click on the name of the Policy to edit, ssloP_Secure_Outbound this example. Click the Add button to add a new rule Name the Rule, O365_Tenant_Restrict in this example. Under Conditions click Select and choose Category Lookup (All). Choose the Custom Category created previously, Office365 in this example. Type the name into the field and it will filter the results. Set the Action to Allow. For SSL Forward Proxy Action select Intercept. Set the Service Chain to the one created previously, O365_Service_Chain in this example. Note: it is critical that the Action be set to Intercept so SSL Orchestrator can decrypt the connection and insert the Tenant Restriction headers. Scroll down and click Deploy at the bottom The changes should be successfully deployed Step #4 Create an iRule From Local Traffic select iRules > iRule list Click Create on the Right Give the new iRule a name, TenantRestrictions in this example Enter the following for the Definition: when HTTP_REQUEST { HTTP::header replace Restrict-Access-To-Tenants "f5labs.com" HTTP::header replace Restrict-Access-Context "ee3dfd2f-6a3b-40d1-9be0-bf8327d81d90" } Note: The restrict-Access-To-Tenants header should contain your Tenant’s domain(s), comma-separated if more than one. Example: “contoso.onmicrosoft.com,fabrikam.onmicrosoft.com” The Restriction-Access-Context header must contain the Tenant ID as shown in the Azure Portal. Click Finished From the SSL Orchestrator Configuration screen select Services. Click the padlock to Unprotect Configuration. Note: Disabling Strictness on the ICAP Service is needed to modify it for Tenant Restrictions header insertion. Strictness must remain disabled on this service, and disabling strictness on the service has no effect on any other part of the SSL Orchestrator configuration. Click OK to Unprotect the Configuration From Local Traffic select Pools > Pool List Select the Office365_Tenant Pool Under Active Health Monitors select tcp and click >> to move it to Available Click Update Note: The Health Monitor needs to be removed because there is no actual ICAP service to monitor. From Local Traffic select Virtual Servers > Virtual Server List Locate the Office 365 ICAP service that ends in “-t-4” virtual server and select it Set the Request Adapt Profile and Response Adapt Profile to None to disable the default ICAP Profiles Click Update at the bottom Click the Resources tab Click the Resources tab > Manage Select the iRule created previously, TenantRestrictions in this example and move it to the left under Enabled Click Finished Step #5 Test the Tenant Restrictions Attempt to login to https://outlook.office.com with your Tenant Restrictions domain. Note: you must attempt to login with an email address and password in order to see the following error page: Footnotes: [1] Detailed information from Microsoft on Tenant Restrictions https://docs.microsoft.com/en-us/azure/active-directory/manage-apps/tenant-restrictions [2] Microsoft Azure portal https://portal.azure.com/
