Tech Paper: Communication Ports Used by Citrix Technologies

This article provides an overview of common ports that are used by Citrix components and must be considered as part of networking architecture, especially if communication traffic traverses network components such as firewalls or proxy servers where ports must be opened to ensure communication flow.

Not all ports need to be open, depending on your deployment and requirements.

Citrix Cloud

The only Citrix component needed to serve as a channel for communication between Citrix Cloud and your resource locations is a connector. This connector might be a Connector Appliance or a Cloud Connector depending on your use case. For more information on which connector you require, see Resource types
.

Connector Appliance

Once installed, the Connector Appliance initiates communication with Citrix Cloud through an outbound connection. All connections are established from the Connector Appliance to the cloud using the standard HTTPS port (443) and the TCP protocol. No incoming connections are allowed.

This is a list of ports that the Connector Appliance requires access to:

Service	Port	Supported Domain Protocol	Configuration details
DNS	53	TCP/UDP	This port must be open to the local setup
NTP	123	UDP	This port must be open to the local setup
HTTPS	443	TCP	Connector Appliance requires outbound access to this port
HTTP	3128	TCP	If the Connector Appliance is set up as a proxy for Citrix Hypervisor updates, it requires inbound access to this port

To configure the Connector Appliance, IT admins must be able to access the admin interface on port 443 (HTTPS) of the Connector Appliance.

Note: You must include https:// at the start of the IP address.

Connector Appliance with Active Directory

Additional ports are required to use Active Directory with Connector Appliance. The Connector Appliance requires an outbound connection to the Active Directory domain via the following ports:

Service	Port	Supported Domain Protocol
Kerberos	88	TCP/UDP
End Point Mapper (DCE/RPC Locator Service)	135	TCP
NetBIOS Name Service	137	UDP
NetBIOS Datagram	138	UDP
NetBIOS Session	139	TCP
LDAP	389	TCP/UDP
SMB over TCP	445	TCP
Kerberos kpasswd	464	TCP/UDP
Global Catalog	3268	TCP
Dynamic RPC Ports	49152–65535	TCP

Cloud Connector

All connections are established from the Cloud Connector to the cloud using the standard HTTPS port (443) and the TCP protocol. No incoming connections are accepted.

Cloud Connectors must be able to connect to Digicert for certificate revocation checks.

Source	Destination	Type	Port	Details
Cloud Connectors	http://*.digicert.com	HTTP	80	Periodic Certificate Revocation List checks
	https://*.digicert.com	HTTPS	443

   • C:\Program Files\Citrix\Receiver StoreFront\Services\SubscriptionsStoreService\Citrix.DeliveryServices.SubscriptionsStore.ServiceHost.exe.config
   • C:\Program Files\Citrix\Receiver StoreFront\Services\CredentialWallet\Citrix.DeliveryServices.CredentialWallet.ServiceHost.exe.config

2. Edit both the config files changing the values for endpoint URIs.

   For example - <endpoint uri="net.p2p://CitrixCredentialWalletReplication"> so any address that starts with net.p2p:// includes the port. You should end up with <endpoint uri="net.p2p://CitrixCredentialWalletReplication:93”> and <endpoint uri="net.p2p://Citrix-Subscriptions-1__Citrix_Store"> becomes <endpoint uri="net.p2p://Citrix-Subscriptions-1__Citrix_Store:93"> and so on for all other net.p2p addresses.

3. Restart the subscriptions store and credential wallet.
4. The local firewall includes rules for allowing per application access, so it is not locked down by port.
