How does ZTNA work?

Hello everybody, 

ZTNA is not clear at all for me.

I'm working from remote and in my Forticlient I've been assigned a tag: 

ZTNA_DEV

I'm not connected to any VPN.

On fortigate, there is a ZTNA Rule:

192.168.1.4 is a ZTNA server that manages a Virtual Machine.

I've also a Firewall policy:

This policy says that all users that whose destination is ZTNA_DEV (192.168.1.4) and have the tags ZTNA_DEV are allowed.

But there is one thing I don't understand. 

I'm working from remote, so I'm not in the enterprise network. How can reach that server?

The firewall policy is saying that the incoming interface is wan1, but how can I reach it?

I know I have the tags, but how is possible that with these tags I should reach the internal network?

Where am I wrong?

Thank you so much!

ZTNA has different deployment methods.

Off-net (remote) clients can still connect and traffic is intercepted by FGT who acts as a Access proxy.

 

This deployment method is called "ZTNA access proxy"

 

  • HTTPS and TCP access proxy solution and architecture
  • Applies to both remote access and internal access
  • No persistent connection (such as VPN) is necessary

 

Below documentation will help you understand better the bigger picture: https://docs.fortinet.com/document/fortigate/7.0.0/ztna-architecture/19197/ztna-access-proxy
