How to open ports in VDA?
To open the ports that the VDA uses to communicate with the Controller and enabled features, specify the /enable_hdx_ports option, in addition to the /enable_hdx_udp_ports option.
What is VDA in Citrix?
The Virtual Delivery Agent (VDA) on each Office PC must register with Citrix Virtual Apps and Desktops. For on-premises deployments VDA registration happens directly with a Delivery Controller, for Citrix Virtual Apps & Desktops Service in Citrix Cloud this registration happens via a Citrix Cloud Connector.

When a user establishes an HDX session to their office PC, the ICA traffic needs to be proxied to the VDA. ICA Proxy can be provided via Citrix Gateway appliances or Citrix Gateway Service.
Where are computing resources shared?
In certain situations, users need to share a set of computing resources, often found in computing labs at schools, colleges, and universities. Users are randomly assigned to an available physical PC.
Can multiple users be assigned to a desktop?
By default, multiple users can be assigned to a desktop if they have all logged into the same physical PC, but this can be disabled via a registry edit on the Delivery Controllers.
What is remote access server?
The Remote Access server acts as an IP-HTTPS listener and uses its server certificate to authenticate to IP-HTTPS clients. The IP-HTTPS name must be resolvable by DirectAccess clients that use public DNS servers.
What is direct access client?
DirectAccess clients attempt to reach the network location server to determine if they are on the internal network. Clients on the internal network must be able to resolve the name of the network location server, and they must be prevented from resolving the name when they are located on the Internet. To ensure that this occurs, by default, the FQDN of the network location server is added as an exemption rule to the NRPT. In addition, when you configure Remote Access, the following rules are created automatically:
What is DNS in DirectAccess?
DNS is used to resolve requests from DirectAccess client computers that are not located on the internal network. DirectAccess clients attempt to connect to the DirectAccess network location server to determine whether they are located on the Internet or on the corporate network.
Do you have to have a public IP address for DirectAccess?
Ensure that you do not have public IP addresses on the internal interface of the DirectAccess server. If you have public IP address on the internal interface, connectivity through ISATAP may fail.
Can DirectAccess use Teredo?
If the DirectAccess client cannot connect to the DirectAccess server with 6to4 or Teredo, it will use IP-HTTPS. To use Teredo, you must configure two consecutive IP addresses on the external facing network adapter. You cannot use Teredo if the Remote Access server has only one network adapter.
Overview
Authentication
- Users continue to authenticate to their office-based PC with their Active Directory credentials. However, as they are accessing over the Internet from outside the office premises, organizations typically require stronger levels of authentication than just user name and password. Citrix Workspace supports different authentication options to be selected including Active Directory + …
Session Security
- Users can remotely access their work PC with an untrusted, personal device. Organizations can use integrated Citrix Virtual Apps and Desktops policies to protect against: 1. Endpoint Risks: Key loggers secretly installed on the endpoint device can easily capture a user name and password. Anti-keylogging capabilitiesprotect the organization from sto...
Infrastructure Sizing
- Note:The following sizing recommendations are a good starting point, but each environment is unique, resulting in unique results. Monitor the infrastructure and size appropriately. As users are accessing existing office PCs there is minimal extra infrastructure needed to support adding Remote PC Access, however it is important that the Control layer and Access layer infrastructur…
Availability
- If the office PC is not powered on with the VDA registered, the user’s session cannot be brokered. Citrix recommends putting in place processes to ensure the machines that users need to connect to are powered-on. If available, modify the PC’s BIOS setting to automatically power on in the event of a power failure. Administrators can also configure an Active Directory Group Policy obje…
User Assignments
- It is important that users are each brokered to their own office PC. Once the VDA has been installed and the catalog and delivery group defined, users are automatically assigned when they next logon locally to the PC. This is an effective method for assigning thousands of users. By default, multiple users can be assigned to a desktop if they have all logged into the same physic…
Microsoft Teams
- If users access Microsoft Teams for voice and video calls, content redirection functionality is required to create a positive user experience. For content redirection to be available when using VDA 1912 or older, it is required to deploy the VDA on the physical PCs using the single-session full VDA installer (standalone VDAWorkstationSetup.exe) with the /remotepccommand line optio…
Common Network Ports
- Similar to any other Citrix VDA, there are a handful of key network ports to be mindful of opening for the system to function. As a reminder, ICA traffic needs to reach the Remote PC Access from the Citrix ADC hosting the external Citrix Gateway. A comprehensive list of ports can be found in Communication Ports Used by Citrix Technologies.
VDA Registration
- Depending on the network topology, the subnet containing the Virtual Apps and Desktops Delivery Controllers might not allow communication to or from the physical PCs. To properly register with the Delivery Controller, the VDA on the PC must be able to communicate with the Delivery Controller in both directions using the following protocols: 1. VDA to Controller: Kerberos 2. Cont…
