Limitations of Universal Zero Trust Network Access

Universal ZTNA does not support IPv6.

Universal ZTNA-enabled devices do not enforce policies for traffic over a site-to-site tunnel.

Universal ZTNA does not support clustered devices.

Universal ZTNA does not support devices in multi-instance mode.

Universal ZTNA sessions do not support jumbo frames.

Currently, universal ZTNA supports only the United States and Europe regions.

Universal ZTNA supports only global VRF.

Universal ZTNA does not support protocols such as FTP or TFP, where the data or secondary connection originates from a server.

For example, an active FTP connection uses a persistent control connection for commands and creates temporary data connections for file transfers. Universal ZTNA does not support such data connections that originate from the server.
