You can use this F5 supported iApp template to configure availability and Secure ICA proxy remote access for Citrix XenApp or XenDesktop environments. This iApp template configures BIG-IP LTM, APM, and AFM for XenApp or XenDesktop services.
When used with BIG-IP APM, this iApp template supports proxy authentication and secure remote access for all XenApp and XenDesktop HTTP-based protocols without requiring a VPN client. The iApp template includes the ability to configure BIG-IP APM for two factor authentication with RSA SecurID, and supports smart card authentication.
