Update existing NetScaler Gateway configuration

If you are updating an existing NetScaler Gateway configuration, it is recommended that you update the configuration manually. For details, see the following sections:

• Update existing NetScaler Gateway configuration for Web and SaaS apps
• Update existing NetScaler Gateway configuration for TCP/UDP apps

NetScaler Gateway virtual server settings

When you add or update the existing NetScaler Gateway virtual server, ensure that the following parameters are set to the defined values. For sample commands, see Example commands to update an existing NetScaler Gateway configuration.

Add a virtual server:

• tcpProfileName: nstcp_default_XA_XD_profile
• deploymentType: ICA_STOREFRONT (available only with the add vpn vserver command)
• icaOnly: OFF
• dtls: OFF

Update a virtual server:

• tcpProfileName: nstcp_default_XA_XD_profile
• icaOnly: OFF
• dtls: OFF

For details on the virtual server parameters, see vpn-sessionAction.

Update existing NetScaler Gateway configuration for Web and SaaS apps

You can use the ns_gateway_secure_access_update.shscript on an existing NetScaler Gateway to update the configuration for Web and SaaS apps. However, if you want to update the existing configuration (NetScaler Gateway version 14.1–4.42 and later) manually, use the Example commands to update an existing NetScaler Gateway configuration. Also, you must update the NetScaler Gateway virtual server and session action settings.

You can also use the scripts on an existing NetScaler Gateway to support Secure Private Access. However, the script does not update the following:

• Existing NetScaler Gateway virtual server
• Existing session actions and session policies bound to NetScaler Gateway

Ensure that you review each command before execution and create backups of the gateway configuration.

NetScaler Gateway session actions settings

Session action is bound to a gateway virtual server with session policies. When you create or update a session action, ensure that the following parameters are set to the defined values. For sample commands, see Example commands to update an existing NetScaler Gateway configuration.

• transparentInterception: OFF
• SSO: ON
• ssoCredential: PRIMARY
• useMIP: NS
• useIIP: OFF
• icaProxy: OFF
• wihome: "https://storefront.mydomain.com/Citrix/MyStoreWeb" - replace with real store URL. Path to Store /Citrix/MyStoreWeb is optional.
• ClientChoices: OFF
• ntDomain: mydomain.com - used for SSO (optional)
• defaultAuthorizationAction: ALLOW
• authorizationGroup: SecureAccessGroup (Make sure that this group is created, it’s used to bind Secure Private Access specific authorization policies)
• clientlessVpnMode: ON
• clientlessModeUrlEncoding: TRANSPARENT
• SecureBrowse: ENABLED
• Storefronturl: "https://storefront.mydomain.com"
• sfGatewayAuthType: domain

Update existing NetScaler Gateway configuration for TCP/UDP apps

Support for TCP/UDP apps in addition to Web/SaaS apps is available starting from NetScaler Gateway version 14.1–25.56. For hybrid deployments, it is recommended to use version 14.1-34.42 to fully leverage TCP/UDP features. If you are updating earlier versions, it is recommended that you update the configuration manually. For details, see Example commands to update an existing NetScaler Gateway configuration. Also, you must update the NetScaler Gateway virtual server and session action settings.
