Hello Community, I hope you're well I stay in process to  deploy  Fortiweb 400 F, but I have doubts about whether it is advisable to place the Frontend and Backend interfaces in separate VLANs, and if you recommend this topology for a future deployment of Adoms, or if the design should be rethought.I attach the Topology.Greetings!!!!   

Hello community,I am currently configuring FSSO in FortiGate to create identity-based firewall policies using Active Directory usernames/groups, and I have a question regarding two different configuration sections that seem related to AD integration.I noticed there are two separate options in the GUI:Security Fabric > External Connectors > FSSO Agent on Windows ADUser & Authentication > LDAP ServersAt the moment, I configured only the FSSO option and it is already learning users/groups correctly from Active Directory.My question is:What is the functional difference between these two configurations? What is each option specifically used for? Is it necessary to configure both for identity-based policies? In which scenarios would LDAP configuration still be required if FSSO is already working?From my understanding so far:FSSO is mainly used for transparent user identification (User ↔ IP mapping) based on Windows logon events. LDAP seems more focused on direct authentication a

Hi Everyone,I am currently working on a FortiNAC deployment integrated with Cisco switches and FortiGate firewall, and I would appreciate some advice regarding the captive portal/isolation VLAN configuration.Environment: FortiNAC version: 7.6.x Cisco access switches FortiGate firewall acting as gateway 802.1X + MAB environment Isolation VLAN configured for unknown/non-domain devices Objective:When an unknown or non-domain device connects to the network: Device should fail 802.1X Fall back to MAB Be placed automatically into the isolation VLAN Receive an IP address Open browser and get redirected to FortiNAC captive portal Current Situation: VLAN assignment is working Device is successfully placed into the isolation VLAN Client receives IP address when DHCP is provided by FortiGate Browser can partially reach the FortiNAC isolation portal However, the captive portal redirection is not fully working correctly.Issues Observed: DNS resolution problem Client cannot re

Dear Community, I have three question about changing parameters in a production environment ha cluster. This cluster has two hw fortigate on one location, which work nicely. Now I have to add a third one but in this time this should be an another location. So I have to prepare the working cluster to add a far third one. 1) I would like to make the Ha cluster more latency tolerant. Current config:  hb-lost-threshold 3 hb-interval 2 hb-interval-in-milliseconds 100ms Is it enough to raise only the hb-lost-threshold, or should I change the hs-interval as well? And more importantly what should be the changeing sequence of these parameteres? Should be change one parameter at once on the primary and secondary member? 2) My dedicated hb interfaces direct connected with cable, and set up that the sync packets use this ha intercae. Now I would like to change this that every packets related to ha goes through a switch/vlan. So I have to add a new ha interface (port1 through switch) with lower pri

Hello, I'm trying to do a lab with a trial version of fortianalizer (7.4.10) and fortigate (7.4.11) and I can't do the connection. When setting the IP of the analizer on the logging settings on the fortigate I get "no connection".They are on the same network, already enable the fgfm on the interface. Can ping both analizer from fortigate and vice versa.  The config that I have on Fortigate:config log fortianalyzer setting    set status enable    set server "192.168.0.102"    set certificate-verification disable    set ssl-min-proto-version TLSv1end The config that I have on Analizer:config system global    set adom-status enable    set enc-algorithm low    set global-ssl-protocol tlsv1.0    set hostname "FAZ-01"    set oftp-ssl-protocol tlsv1.0    set ssl-low-encryption enable    set timezone 91    set usg enableend Log from analizer

Hello, I am trying to update FortiSIEM content version from 901 to 908, but I receive a “server unreachable” error during the update.For testing, I allowed all-all access on the firewall for FortiSIEM, but the issue still persists.Has anyone experienced a similar issue? Are there any specific URLs/FQDNs, ports, or log files that should be checked for FortiSIEM content updates? Best Regards,İsmail ÜREK

I want to make Forti Sandbox take copy of all internal mail which sent between the staff internally and scan it “URL & Attachments”How can I do this step by step on Forti Sandbox ? 

The documentation states you can define multiple certificates in an SSL profile in replace mode and it will compare the server name identification (SNI) and the common name (CN) with the certificate list in the SSL profile, and use the matched certificate as a replacement. If there is no matched server certificate in the list, then the first server certificate in the list is used as a replacement.However, this does not seem to work if you are using wildcard certificates. I have an SSL profile that has multiple separate wildcard certificates defined in the profile that is used to protect a highly available reverse proxy for several domains and subdomains.e.g. SSL Profile in replace mode has separate wildcard certificates for *.abc.net, *.abc.com, *.io.abc.com, *.abc.org, *.bbc.com, *.bbc.org. If a request comes in with an SNI of www.abc.com it will instead return the first certificate *.abc.net as the exact CN name matching does not match the wildcard.Has anyone else experienced this is

Hi ti all, Our FortiGate 50G is protecting 2 different routers from 2 different ISPs. One is plugged to Wan and the other to Lan1 (=Wan2). Domestic use network. Only ethernet. No WiFi. A few days ago, I tried to protect a TV decoder with the FortiGate. Creating the multicast policies, I have surely changed something I should not have to. The TV decoder was plugged into lan 2 which belongs to a Vlan switch (called "lan". Members: lan 2 + lan 3). This Vlan provides internet from only one of the routers Now I have the following symptoms: - When using this routers's internet and plugging the ethernet cable to my computer, my Airbook gets an auto-assigned IP first (yellow led) and, after 30 seconds, it switches to a normal IP (green led): Internet is available then. This symptom happens only with one of the routers (plugged to lan2 or lan3... Where the TV decoder was plugged to). I tried to disconnect "STP". then the symptom disappears. But comparing with the old configuration file, I notic

All Internet access must go though a proxy server in my company.  Now I am testing to use FortiClient EMS for my FortiClient users.  But I found that FortiClient cannot connect to FortiClient EMS for telemetry connection via a proxy.  Any work around can make this work?

I am working as an intern at a startup and the website I am handling https://www.gazfull.com/ is being flagged as malicious by FortiGuard and getting blocked.There is no intentional malicious content on the site. We want to fix the root cause instead of just requesting whitelisting.What are the common reasons FortiGuard flags a website as malicious?Are there specific security loopholes, misconfigurations, headers, SSL issues, third-party scripts, or deployment patterns that typically trigger this?Also, after resolving potential issues, what is the correct process for requesting reclassification/whitelisting with FortiGuard?Any guidance on debugging this systematically would be really helpful.

Hi everyone,We are using a FortiGate 60F firewall with SSL VPN configured for remote access, and users connect via FortiClient VPN.Issue DescriptionSSL VPN connects successfully every time via FortiClient Users receive VPN IP and session remains connected without disconnecting Internal resources (servers, RDP etc.) are intermittently not reachable When the issue occurs, VPN reconnect does NOT resolve the problem Users must either wait or restart system/network stack, but behavior is inconsistentKey ObservationThe issue does NOT occur on all clients at the same time Some users continue working normally while others lose access randomly Affected clients remain “connected” but cannot reach internal network resources Once the issue occurs, re-establishing VPN session does not fix itWhat we have checked so farVPN tunnel remains up with assigned IP Issue appears random across users and sessions No clear pattern related to user group or time   Has anyone faced a similar issue on FortiGate SSL
