Hi there,

I have 2 users, sometimes one user is unable to receive trafic and sometimes both are unable to receive trafic

The configuration is the same, here are two screenshot frome the same VPN and diffrent workstation

 

Best Regards

Hi @slimsellami 

Did you configure a firewall policy?

Is the traffic hitting the proper firewall policy?

Please can you provide us with the Forward logs?

 Log & Report > Forward Traffic (try to reproduce the issue with the specific user IPs)

Best regards,

Erlin

Sure,I have a configured policy the problem is that the same user can connect from a workstation but not from another

there is only one VPN and the traffic is hitting the proper policy

Both devices are the same? 
For e.g both are windows 10 with the same version of FCT?

Hi ezhupa,

the one which is working is Win11 ans FCT 7.2.4

and the one which is not working is Win10 and FCT 7.4.0

[ezhupa]

Try with the same version of FCT on the Windows 10 machine (so 7.2.4)
If it works then we can rule out the FCT version as the issue here.

Where can I choose the FCT version ?

[ezhupa]

You would need to uninstall FCT and reinstall the new FCT version:
Ref documents:

https://docs.fortinet.com/document/forticlient/7.4.1/administration-guide/7962/uninstalling-forticli....

I believe the version you can choose in the fortinet support portal and download a particular version (if you have licenses for it)

Hi ezhupa,

Same problem with the Version 7.2.4

I already tried to disable Win Defender to avoid any confusion
