Tips for implementing a VMware Horizon View Security Server

A security server is a special instance of View Connection Server that runs a subset of View Connection Server functions. You can use a security server to provide an additional layer of security between the internet and your internal network. A security server resides within a DMZ and acts as a proxy host for connections inside your trusted network. 

Setting up a VMware Horizon View Security server can be a challenging task because you have to deal with firewalls and some ports that’s need to be opened between the servers. Here are some tips for implementing a VMware Horizon View Security server:

  • A Security server resides within a DMZ
  • The security server is not a member of the Active Directory
  • Create or obtain a signed certificate for the Security Server from a  trusted Certificate Authority. More information about the certificate options can be found here.
  • To allow tunneling of the PCoIP protocol from the Security Server  to a Connection Server, configure the PCoIP Secure Gateway. More info can be found here
  • Verify that Windows Firewall with Advanced Security is set to on in the active profiles. It is recommended that you turn this setting to on for all profiles. By default, IPsec rules govern connections between security server and View Connection Server and require Windows Firewall with Advanced Security to be enabled
  • Back-end firewalls must be set up to support IPsec. If you have a back-end firewall between security servers and View Connection Server instances, you must configure firewall rules to allow the connections to work. More information: See “Configuring a Back-End Firewall to Support IPsec ” in the View Installation guide.
  • Windows Firewall with Advanced Security must be enabled on Security Server and View Connection Server hosts.  By default, IPsec rules govern connections between the View security server and View Connection Server and require Windows Firewall with Advanced Security to be enabled.  Best choice: Set Windows Firewall with Advanced Security to on before you install the View servers. Make sure it’s on for any active profiles; better still, set it to on for all profiles.  Alternative: Before you install security servers, open View Administrator and disable the Global Setting, Use IPsec for Security Server Connections, by setting it to no. (This is not recommended.)

  • The firewall rules that needs  to  be used can be found here. I made a drawing (based on VMware Horizon View Security server version 5.2) of a single View Security server that list the ports and rules that needs to be opened between the servers:

VMware View firewall poorten

 

(*1) HTML Access uses TCP port 8443 for client connections to the Blast Secure Gateway

(*2) Enable this port for firewalls that use NAT. For non-NAT firewalls use the ESP protocol.

(*3) Enable this port  if you use VMware Horizon View HTML Access, security servers connect to View desktops on HTTPS port 22443 to communicate with the Blast agent.

  1. With regard to the BLAST protocol requirements.

    You show the Security server needs 8443 port opened to the paired connection server, however this is not mentioned in VMWare’s documentation ?

    I’m currently setting up HTML5 access externally and wanted to confirm this ?

    I know the Security saerver needs 22443 to the Desktop pool, but is 8443 to the connection server required ?
    here is the vmware documentation http://pubs.vmware.com/view-52……..

  2. Hi Ivo 😉 !

    I have a question regarding the View Security server.
    In my onfiguration, I only open the ports below : TCP 80, TCP 443 and TCP/UDP 4172.

    there is not redirection port done by the router, so normally everything should be ok.

    The only thing i havent done, it s to resolve my Public IP… so I dont have and DNS…

    Do you thing that s why I cannot access via my horizon client to my horizon Virtual Machine ?

    (because when I type my public IP in https, I can show the vmware Horizon page…)

    Thanks for your answer 😀 !

    Regards.
