Hi everyone,I’m currently trying to connect to an older FortiGate device (FortiOS 5.4), so I need to use an older version of FortiClient (6.0 or 6.2).Since the device is EOL, I’m unable to download the installer from the official Fortinet support portal. I managed to get the 6.2 online installer, but it fails during installation with errors related to an invalid digital signature and MSI error code 2711.Would anyone be able to share a FortiClient VPN 6.0 or 6.2 offline installer (full package) or point me to a reliable source?I would really appreciate your help.Thanks in advance!

How do i find the status of All VPNs in FortiAnalyzer ?

Hello Fortinet Community, I would like to inquire whether it is possible to implement a VPN chaining (nested VPN) scenario using FortiClient. Use case:We have a requirement where access to a client VPN is restricted to a specific public IP address (e.g., 193.40.X.X). When connecting from our office network, we are able to access the client VPN successfully because our traffic originates from this whitelisted IP. However, we would like to achieve the following setup: Connect from a remote location (home) to our office VPN using FortiClient.Once connected, establish a second VPN connection (also via FortiClient) to the client environment.Ensure that the second VPN connection is seen as originating from the office public IP (193.40.X.X). Questions: Does FortiClient support running multiple VPN tunnels simultaneously (VPN over VPN / nested VPN)?Are there any supported configurations or best practices to achieve this setup?Are there specific requirements (e.g.,

Hello all. Looking for anybody who has run into this issue and may be able to provide guidance.We have a pair of FGT 70Gs running 7.4.9 connected to a stack of 148F FSWs running 7.2.5. This is our standard stack and we run it at dozens of sites.We have NAC enabled via the built in managed FSW setting (not FortiNAC). We add devices via NAC policies individually and via wildcard filters such as Vendor name and device type (Example: IP Phone). Our switchports are configured in NAC mode and based on the device that plugs in, the dynamic VLAN will assign to what's configured in the NAC policy.Anywhere from a couple to a few times a day, users with devices plugged into these NAC-mode switchports say their devices are doing network hard down, and then coming back up moments to minutes later. I checked logs and am seeing that the entire NAC MAC address cache appears to be deleted out and then added back, all at once but separated by short periods of time. This aligns exactly with when the issu

When using the ACME client in FortiWeb v8, does it automatically re-use the same private/public key for renewals? or does it issue a new key on each renewal? 

In FortiAnalyzer, I have one ADOM with 200 firewalls and another ADOM with 5 firewalls, but on all the firewalls regardless of the ADOM, I can't see the logs in security events > WebFilter, for example, only from memory.Also, in FortiAnalyzer, in FortiView the tabs Traffic, Shadow IT, Applications and Websites, VPN, and System are grayed out, making it impossible to select them.Could this be a license issue or some configuration parameter?

I have just acquired a fg60e, i realise it's end of life but i plan on using it just for learning firewalls, vlans etc so don't need full licence for extras, i plan on doing cisco & fortinet free courses to understand more about networking & security.Tonight i have got it setup & connected to the internet & noticed it's running fw v 6.0.3, i realise it's old but in your opinions would this be adequate for learning the basics of fortinet OS or can you suggest a more up to date stable fw version.

HelloWe are using a FortiWeb cluster as a VM for our customer. The backend servers of our customer's customers are gradually being migrated to this FortiWeb cluster from a Sophos UTM 9. We also operate the Sophos UTM 9. The first backend servers are already running on the FortiWeb VM and access is successful. The challenge now is to migrate the backend servers that use SSO login via KeyCloak with Azure to the FortiWeb cluster. We have configured a test backend server for this purpose. Our customer  has configured KeyCloak (plain vanilla without any special configuartions) on his environment. We have configured the Azure parameters on our side in Azure. When accessing the test backend server via Sophos UTM 9, everything works without any problems. When accessing via FortiWeb,  I can authenticate and then it's pending. After round about 20 seconds comes '404 Not Found'. What did we overlook or configure incorrectly in the FortiWeb cluster configuration?Thank you in advance for

We have just migrated to FortiClient EMS 7.4.5 LinuxVM from FortiClient 7.2.12 WindowsVM. In that process we are trying to move from Active Directory to Microsoft Entra for controlling Manage Deployments. While deployments are working fine from the Active Directory side, the issue we are seeing is that Windows devices from the Entra side are not and showing "Unsupported Operating System"All these devices are Windows and have been onboard from Intune and as this is a hybrid environment. The same device works fine on the Active Directory side.I am sure I am missing something, but I have been through it a few times and I can see nothing wrong from the setup documents.Anyone have any idea what I am missing?

Hi Everyone.I have a customer who has a FGT 80E with full UTM features. The main web policy has Web Filtering, IPS, AV and SSL inspection Security Profiles assigned. The end users are reporting that randomly they will get redirected to gstatic.com/generate_204. Looking the browser history under gstatic.com/generate_204 it references "Fortinet DNS Service" which made me wonder if it was one of the Security Profiles causing the issue. I removed all profiles from the web rule and the issue still occurred. I then came across this KB (https://kb.fortinet.com/kb/documentLink.do?externalID=FD36680) regarding  QUIC (Quick UDP Internet Connections) and as the customer had reported that the issue was with Google Chrome, I asked them to implement Method 1 from the KB on a machine that was experiencing the issue. Unfortunately this did not resolve the issue. I have looked at the logs on the FGT and there is nothing there to help me. I am not convinced its a FGT issue (although the r

Hi,  Does anyone experience based on this article?https://community.fortinet.com/t5/FortiGate/Technical-Tip-Understanding-the-log-message-User-shutdown-the/ta-p/301290 Scope is for 7.2.5 and above. The current version is 7.0.12 May I know if this is false positive?  Thanks!

I have a question regarding the Web Filter Function.Currently, I have enabled the Web Filter Function by configuring "certificate-inspection" as the SSL inspection.However, because the FortiGate certificate has not been manually imported to the client PCs, a certificate error screen is displayed when communication is blocked.Therefore, I have configured the following settings to prevent the alternative message screen from being displayed:[Settings]config web-proxy explicit　set https-replacement-message disableend Since the connecting client PCs are numerous and unspecified, I do not want to manually import certificates individually.I would like to display an alternative message screen instead of a certificate error when communication is blocked.If there is a way to achieve this, could you please advise me?

Hi Fortigate,My fotigate is 7.2.11 build 1740.I understand 7.2 is out of support in September. How do we upgrade from 7.2 to 7.4?regardsJohn Zen@@

Hi All, I have doubt if we can achieve below requirement.  Fortigate integrate with Clearpass/ISE for ZTNA authentication , but the user identity is at Entra ID(no local AD). I knew that Fortigate can direct integrate with Entra ID using SAML, but client insist to use Clearpass/ISE as authentication server(lets not challenge client why at this moment).  Flow should be ZTNA Client > Fortigate > Clearpass/ISE > Entra ID Question : Can this be done ? Or can i say this can be only done if FortiAuthenticator is used instead of Clearpass/ISE ?

Hello,I've deployed policies from my FMG to my FG, and although the deployment was successful, the changes aren't “visible” on the FortiGate.Is this normal?I'm working in a lab environment where my FMG is running version 7.41 and my FG is running version 7.2.5.Cheers :)

Can Site-to-Site VPN between HQ and a Branch be implemented with overlapping subnets? In this case, four subnets are going to be used at each site. Therefore, I would like to know if overlapping works fine for more than one single subnet. Thanks.

do the fortiswitch's support stacking ? i am speaking of traditional stacking where all switch are managed via single ip address and I can configure ports from any stack member thru a single mgmt ip .  what about stacking bandwidth? do we have any dedicated stacking ports or is everything done thru the ports on the front of the switch?  example if i have a 3 x 24 port 1G copper switch with no uplink ports how would i stack these 3 switches? Is daisy chain my only option?

Hello, I'm running FortiManager-VM64-KVM v7.4.10 build2278.I was wondering how to create an correlation handler event to trigger for when a specific account logs into FortiManager. I've tried getting it to work from this log entry (FortiManager > System Settings > Event Logs), but it's not triggering the event even though the account successfully logs in. 2026-03-31 08:18:00 tz="+0100" log_id=0001010018 type=event subtype=system pri=information desc="User login/logout successful" user="myuser@domain.com" userfrom="SSO(IP_address)" msg="User 'myuser@domain.com' (myuser@domain.com) with profile 'Super_User' login accepted from SSO(IP_address)." adom="root" adom_oid=0 session_id=62498 operation="login" performed_on="SSO(IP_address)" changes="'myuser@domain.com' login accepted from SSO(IP_address)" adminprof="Super_User"Does anyone have a template for this to work?

Based on this article herehttps://community.fortinet.com/t5/FortiGate/Technical-Tip-How-to-enable-EAP-TTLS-for-IPSec-IKEv2-tunnels-in/ta-p/408602 I know you've tried more than once to make the tunnel up with IKEv2 and with LDAP Authentication and it didn't work. First I would like to thank to my friend @Mohamedh219 for his amazing effort getting such article Here is a solution that worked out with me based on this Japanese article:https://licensecounter.jp/engineer-voice/blog/articles/20260331_fortigate_ipsec_vpnikev2_-_ldapforticlient_vpn_-.html  All you have to do is enabling the transport protocol to be using TCP instead of UDP for the tunnel's configuration, and set the ike tcp port to a port that you're 100% sure it's opened by the ISPs (for example 443 which is used for web browsing) .. Check image below  Also from the FortiClient perspective .. go to the VPN settings for the configured IPSEC VPN .. Go to Advanced settings under p

We're setting up ZTNA and one of the hurdles we have run in to is file shares - currently we're mapping network drives to our local domain name (eg \\contoso.lan\Share)I've been able to verify share access via a specific server FQDN but when i try to set up "contoso.lan" as a FQDN address on the firewall (verified it appears in HOSTS file), access is lost which was expected. Contoso.lan resolves to the DCs and not the file share servers.I didn't find any documentation or examples for this specific scenario and scratching my head how I could get this to work.Has anyone run in to this or have any suggestions to look in to or try?

Hello,Does anyone have the official list of FortiGate models supported by FortiOS 8.0.0?Also looking for the recommended upgrade path to reach 8.0.0 from 7.0.x and 7.2.x.Thanks in advance.

I've a question regarding the Transparent proxy policy and Proxy-based inspection policy, since the Transparent proxy policy and the proxy-based policy are doing the same thing i mean the FortiGate buffering the traffic and the client communicate with the FortiGate and the FortiGate communicate with the remote server (2 Connections - Man in the middle topology) Why we use Transparent proxy then since the proxy-based inspection mode policy has the same function?

Hello everyone,I am currently experiencing an intermittent connectivity issue affecting multiple macOS devices in our environment.The devices connect successfully to the WiFi network through FortiAP units (mostly model 231K). However, after some time, they suddenly lose network connectivity and internet access, even though they still appear as connected.From the FortiGate perspective, the affected devices are still visible under the WiFi Clients list, but they are unable to pass traffic properly.We have already performed extensive troubleshooting, including:Reviewing logs and event records on the FortiGateOpening a ticket in TACTesting different configuration adjustments on the SSIDModifying FortiAP operational profiles and performance-related settingsDespite all these efforts, the issue persists.It is also important to highlight that this behavior has been observed across different MacBook models, which suggests it is not hardware-specific.Has anyone experienced a similar issue with m

Hi Team,We would like to highlight a recurring security concern we’ve observed across multiple FortiGate deployments and incident investigations.During the initial setup of FortiGate (FortiOS), the device allows login without a predefined password and prompts the user to set one. In practice, many users end up configuring very weak passwords such as:adminadmin@123P@sswordpass@123These passwords are already available in public leaked credential lists and are commonly used in brute-force attacks.In our recent investigations, we have seen multiple FortiGate firewalls get compromised due to weak admin passwords.Attackers were able to:1.Gain admin access2.Create full-access SSL VPN configurations3.Execute ransomware inside the networkWhen these incidents happen, most customers assume:“FortiGate firewall got hacked”However, the actual root cause is weak password configuration, not a product vulnerability.This creates a reputation issue where the product is blamed instead of the misconfigurat
