Howdy,
As it look like KEMP is going to be one of the official ways to publish your Lync 2013 URLs, Mobility and web Services.
So I looked around contacted KEMP to know what can this solution provide for us, as we are planning to replace our TMG solution with another Reverse proxy solution.
They recommended that I download the new VLM-5000 (Virtual LoadMaster) and give it a try. So I did that, I created a Virtual Lync Lab on Hyper-V and downloaded the new VLM-5000 from here: http://kemptechnologies.com/emea/server-load-balancing-appliances/virtual-loadbalancer/vlm-download
Good thing about that is they give you the option to choose your virtualization solution (Hyper-V or VM or Vbox…etc.)
I created two virtual VLANs on my Hyper-V, One for Internal Network, and one DMZ, the DMZ I will use to give IP-address to the VLM which will be NAT-ed to Public IP on my Firewall.
Deploying VLM-5000 & Basic Configurations
So once you downloaded the VLM use the guide comes with it to Import the Virtual machine in Hyper-V and attach the correct Network to the VM.
· After turning on the VM, and the OS is booted, you should find the IP-address of VLM in the Screen as shown here
· By default VLM if couldn’t contact your DHCP get the IP-address 192.168.1.101
· Use the URL https://192.168.1.101/ to access the web portal of your VLM
· The default username and password are
Username: bal
Password: 1fourall
· Once in, in the left Menu, go to “Server Configuration” and under “Interface” click on the Network Card eth0 to configure it
· Now configure the correct IP-address you want to assign to the VLM in your Internal Network, in my case it’s 172.19.69.56/22 (/22 is the subnet of the network)
· Next configure the VLM hostname, DNS IP-address, and name
· So in Left menu, under Local DNS Configuration click on “Hostname Configuration”
· Assign a Hostname for your VLM
· In Left menu again, click on “DNS Configuration”
· In First Field “DNS NameServer IP address” put the IP-address(ES) of your DNS servers.
· In the Search Domain Field, put the name of your Domain
· In left Menu, click on “Route Management”, and under it click on “Default Gateway”
· Put the IP-address of your default gateway.
· Under system Administration you can change the Password of the default account of the VLM
Publish Lync (Create a Virtual Service)
To Publish Lync URLs or mobility you need DMZ IP-address that is NAT-ed to a Public IP-address. With KEMP Creating a Virtual Server is the way of configuring a DMZ IP-address to be used for Lync URLs or Mobility, so basically you are configuring a DMZ IP-address not a virtual server.
So I will be using an IP-address in the DMZ of 192.168.1.222 which will be NAT-ed to a public IP-address using my firewall.
· So in Left menu up, click on “Virtual Services”
· Then click under “Virtual Services”, “Add New”
· Put the DMZ IP-address you will be using
· Set the Port to 443
· And give the name of your services “LyncWeb, LyncMobility…etc.”
· Click “Add this Virtual Service”
· This should takes you automatically to the configuration Page of the Virtual service you just created
· Make sure the Service name is correct, and that HTTP/HTTPS is selected
· Expand the “Standard Options” menu
· Uncheck the “Transparency” box, and Check the “Use Address for Server NAT”
· Next, Expand the “SSL Prosperities” menu and check the box says “Reencrypt” you will get a warning pop up, click ok
· Click on Add new and add the Public Certificate your created
· And add the Intermediated Certificate too.
· Now jump to the “Real Server” menu and expand it
· Click “Add new”
· Add the IP-address of your Lync Front-End Server
· Change the Port to 4443
· Forward method should be “NAT”
· Click “Add this Real Server
· And back on the “Real Server” page, make sure that the port is changed to 4443
· Make sure th
· at “HTTP Method” is set to “GET”
Well that is all you need to configure do.
