Dyslexia Thinking + Thoughts on the power of Citrix SDWAN captured in a Blended Doodle

SD-WAN is a Complex Subject, I’ll Simply It
I decided to put together this blended doodle together to better explain Citrix SD-WAN, how it works in a visual illustration to have more meaningful conversations and discussions. I picture can tell a thousand micro stories and the big picture here depicts a simple story which tells you the IT + Business value of SD-WAN including the why and it also tells an important industry story often never told which is that implementing ANY SD-WAN is NOT frictionless with an out of the box experience, it takes effort but once that effort is done and done right then Citrix SD-WAN’s Zero Touch strategy will takeover and make it frictionless from IT to the branch to key workers at home. Another top of mind reason to consider as a real world field example is that you simply cannot do a (Citrix) SD-WAN PoC 99.5% of the time to evaluate it. Wait what? Why? It’s always going to be a pilot, and the why is simple you are taking over co-control of an organisations underlay network to create an SD-WAN overlay network, while inserting (Citrix) SD-WAN packets into the organisations network fabric. This is a fact of every SD-WAN vendor in the marketplace.

Technically Understanding Citrix SD-WAN
The following links below will help you better understand Citrix SD-WAN’s terminology, strategy and technical acumen and thinking when deploying, managing and monitoring an SD-WAN overlay network bonding two or more underlay networks e.g Business broadband and 4/5G LTE internet circuits together into a single seamless internet pipe, while giving IT back control over its WAN including allow them to better measure meaningfully your MSP/ISP internet circuit providers performance including complete vs. brown outages, while visualising and seamless failover due to packet loss in a single direction with any internet circuits.

Why this Blog Article?
I’ve had a lot of cloud 1st strategy conversations with IT Pro’s, Citrix SysAdmins & organisations alike recently so I thought everyone whom is searching for how-to front XenApp with an Azure NetScaler could benefit from this blog post :-). This blog post covers a how-to even with NetScaler in single IP mode to achieving https://FQDN (Image 2) for the gateway vs. https://FQDN:8443 (Image 1) when deploying NetScaler in Azure (ARM).

Deploying NetScaler 11.x.n using Azure Resource Manager (ARM)
1. Login to https://portal.azure.com
2. I presume that you have setup a your network, IAM if not refer to https://azure.microsoft.com/en-gb/get-started/ for getting started how-to from Microsoft.
3. Click on + New in the top left of the ARM web ui and type in NetScaler and select NetScaler VPX Bring Your Own License or for a quick review check out – https://azure.microsoft.com/en-gb/marketplace/partners/citrix/netscalervpx110-6531/.
4. Click Create
5. Enter in a name for your NS virtual appliance e.g ne1nug01 and select the VM disk type
5. Enter in a username and choose auth to be either SSH public key or Password I choose password to access the NS Admin WebUI for simplicity of all readers of this blog.
6. Select your chosen of default Subscription if you have more than one and then select your existing Resource Group where you XenApp 7.11+ environment and XenApp 7.11+ VDA Workers and your mgmt. VM running AD/DNS server resides. Remember I am keeping this simple as it’s intended for PoC’s only!
7. Continue to select your chosen Azure instance for NetScaler I choose DS2_V2 Standard which consists of 2 Cores, 7GB of RAM.
8. Select your storage account, virtual network & subnet e.t.c and high availability set then click Select to continue.
9. Review your purchase of NetScaler and then click Ok to purchase and Azure will begin building your NetScaler VPX in your Azure chosen subscription which will take no more typically than 10 minutes.

Setting up & Licensing your NetScaler on Azure
Firstly be aware that when deploying a NetScaler instance on Azure for virtual apps & desktops you’ll be setting up NetScaler to run in single IP mode (YES!) which means that you’re connecting to internal TRU resources on the NetScalers IP addr (NSIP) but you connect using different ports e.g ICA Proxy on 8443 so lets begin with the setup.

1. Login into your NetScaler using the NS Admin Web UI do not provide a SubnetIP Addr (SNIP) just select Do It Later and proceed with the initial setup as per normal.
2. Now that you have setup your NetScaler you need to license it so remain logged into and open a new tab in your browser of choice and Google “Citrix Eval Store” or save this link – http://store.citrix.com/store/citrix/en_US/cat/ThemeID.33753000/categoryID.63401700
3. Select under Networking -> NetScaler ADC
4. Next select the following model “VPX” select variation e.g “Platinum 1000” select duration e.g “90 Days”.
5. Complete the onscreen process note that you will require a .Citrix.com account or you need to create an account.
6. Once you receive an e-mail with your key/code head over to at https://www.citrix.com/account/toolbox/manage-licenses/allocate.html or goto and select find and allocate your licenses or look for the licensing button (link) and select it.
7. If your key/code it not visible select “Don’t see your product?” in text in/around the top right-hand side. A pop-up appears now enter in the code provided on e-mail from the Citrix Eval Store e.g “CTX34-XXXXX-XXXXX-XXXXX-XXXXX” and continue.
8. You will need to enter in the Host Id of your NetScaler it can be found once logged in using the NS Admin Web UI “NetScaler -> System -> System Information” then look under the heading “Hardware Information” and you find “Host Id” copy and paste it into the required field and then download the license file.
9. In the NS Admin Web UI click the cog icon top right then select licensing and upload the license and select to reboot the NS to apply the license.
10. Log back in and enable the features that you require e.g right click on the “NetScaler Gateway” and select “enable” e.t.c

Setup Type Choice 8443 Default without an Azure L/B for XenApp using the XenApp/XenDesktop Wizard
Now that you have setup NetScaler within your Azure subscription in your chosen region you’re ready to begin setting up NetScaler to front virtual apps & desktops (Server OS 2012 R2 or 2016) powered by XenApp 7.11+.

Sample Text Based Diagram

User Azure NetScaler StoreFront XenApp
https://FQDN:8443/ ↔ Accepts requests from Azure to NSIP on https://8443 (Single IP Mode) Accepts requests on the Gateway & Call-back FQDN on https://FQDN:8443 Accepts & launches user’s virtual app(s) & desktop(s) as requested

1. Login to your NetScaler VPX click “Settings -> Licensing” now check that License type is Platinum and Model ID 1000
2. Select the XenApp/XenDesktop wizard and review the prerequisites carefully prior to continuing BUT in summary you’ll need an SSL Cert, LDAP service account + details, XenApp 7.11+ environment with StoreFront.
3. Enter in the static IP addr assigned by Azure or OTHER METHOD of your NetScaler VPX YES that’s right!
4. IMPORTANT STEP: Change the default port of 443 to 8443 on the Gateway IP addr
5. Set Up the rest of the XAD wizard as normal
6. IMPORTANT STEP: Setup StoreFront to allow remote access however the configured default gateway and Call-back FQDN addresses MUST include 8443 e.g https://go.x1co.eu:8443 instead of just https://go.x1co.eu
7. Setup external DNS entries e.g go.x1co.eu to point to your NetScalers static IP addr found in the Azure ARM Web UI and once you have verified it is functioning correctly using a shell (IPCONFIG /FLUSH after settin-up the DNS entries waiting 10-15 min depednant upon your ISP) the open up an internet browser and type in e.g https://go.x1co.eu:8443 and dont forget the :8443 at the end of the FQDN.
8. Attempt to login either using sAMAccountName e.g username or userPrincipalname e.g username@x1co.eu and then you should be able to successfully login and launch your virtual apps & desktop as per the below image.

Setup Type 443 for XenApp using an Azure Load-Balancer & the NetScaler XenApp/XenDesktop Wizard

Sample Text Based Diagram

User Azure Azure Load-Balancer NetScaler StoreFront XenApp
https://FQDN/ https received request and forwarded to NetScaler on https://FQDN:8443

 Accepts requests from Azure L/B on https://FQDN fwd to NSIP on https://8443 (Single IP Mode) Accepts requests on the Gateway from HTTPS://FQDN but the Call-back FQDN is on https://FQDN:8443 Accepts & launches user’s virtual app(s) & desktop(s) as requested
↔ https://FQDN ↔ AzureL/B ↔ NetScaler:8443 NetScaler https://FQDN:8443 ↔https://FQDN StoreFront StoreFront Call-back https://FQDN:8443
StoreFront configured NetScaler Gateway https://FQDN

1. If you are choosing this option as your preferred lets hope then complete steps 1-5 and also step 7 to save you time!
2. IMPORTANT STEP: Setup StoreFront to allow remote access however the configured default gateway MUST BE e.g https://go.x1co.eu NOTICE NO :8433 YES not :8443 here. Now on the call-back FQDN addresses YOU MUST include 8443 e.g https://go.x1co.eu:8443 instead of just https://go.x1co.eu otherwise fronting NS with an Azure L/B to acheive HTTPS://FQDN for the XAD Gateway (ICA Proxy) will NOT WORK!!!!
3. Now switch to the Azure ARM Web UI. You should probably read the following useful resources – https://azure.microsoft.com/en-gb/documentation/articles/load-balancer-overview/ and for PowerShell creation check out – https://azure.microsoft.com/en-gb/documentation/articles/load-balancer-get-started-internet-arm-ps/ for any Citrix consultants out there.
4. Azure Load-balancer and click on the “+” at the top and provide a “Name” and for the type choose “Pubic” and select your Azure “Subscription” “Existing Resource Group” and its location (Same as NetScaler deployed instance) then click “Create”
5. Now it will list the available public IP addr just select the “+”
6. Enter in a name and choose your assignment choice “Dynamic” vs. “Static” and click OK.
7. Azure will then provision your Azure L/B (Wait….Maybe coffee or tea break?)
8. Once created select your Azure L/B
9. Select “Backend Pools” enter in a name then choose your availability set and then your VM’s or VM e.g NetScaler. Azure will then provision your Azure L/B with a backend pool (Wait….)
10. Select “Frontend IP Pool” click “+” enter in a name then choose your IP addr e.g NetScaler VM and then enter in a name (all names should differ makes identification easier so a good naming convention helps 🙂 now) and choose your assignment choice “Dynamic” vs. “Static” and click OK (Updating….)
11. IMPORTANT STEP: Select “Inbound NAT Rules” select the resource from your Frontend IP Pool list from the previous point (10). Select the service “HTTPS” and port to be 443 then select the target “NetScaler VM” and then vErY iMpOrtAnt select under “Port Mapping -> Custom” and in the “Target Port enter in 8443” and click save. (Wait…)
12: Now navigate to https://FQDN and attempt to login either using either sAMAccountName e.g username or userPrincipalname e.g username@x1co.eu and thereafter you should be able to successfully launch your virtual apps & desktop published by XenApp 7.11+. The below image represents the end goal when fronting an Azure NetScaler in Single IP Mode with an Azure Load-Balancer as per the below image.
