Wrong IP Adress on Adapter when connecting FortiClient

[AlexanderB]

Hey everyone,

a user in my company has a problem with windows 11 and FortiClient.

When he connects his FortiClient sucsessfully, he doesnt get any data traffic, probably because of a wrong IP configuration. We already tried to reinstall version 7.2.8 and also uninstalled it and installed 7.2.6 -> same error even after upgrading 7.2.6 -> 7.2.8

On the attached screenshot you can see that FortiClient shows a different IP adress then the adapter in cmd with ipconfig, to me that looks like the error.

The exact same constilation between Windows 11 and FortiClient 7.2.8 worked for the user the last 5 months until today.

When you google something the following message appears:

He is currently the only user with this issue, other users can work perfectly fine.

I hope you guys can give me a solution.

Best reguards,

Alex

You have noticed the typo? Or should it actually be time.cloudfare.com? I would assume it should be time.cloudflare.com and I also assume your clients point to time.cloudflare.com because that resolves to 162... address

Hi shikapa2,

where do you see the typo? Normaly our FortiClient Profile contains our own DNS Server IP adresses, where do you see that the client resolves to cloudflare?

I think the problem is that FortiClient doenst edit the network adapter to the IP & DNS Server's we configured in the profile so it takes a 169.254. adress which wont work. But I dont know how to fix that issue... if thats the one.

BR,

Alex

Good day,

we have the same problem on multiple computers with version 7.4.3.1790. 

Reinstall FortiClient, but no result.

Installed OS Windows 11 23H2.

FortiClient connect to SSL VPN sucessfully, but no incoming traffic detected. 

FortiClient not change IP in adapter settings after connect.

Any ideas how resolve this issue ?

We figured out that there's 802.1x enforced for all ethernet adapters trough Intune. Once disabeling that, it worked.
