Dear guys, one of my appliances which is installed in another office, encounter a problem . i can' t connect to it' s Web gui while in this situation the appliance works fine and all the traffics passes through, depends on policies. so i decided to change the HTTP port number via console connection and it was ok immediately after doing that, but the issue happened again , it' s happening on a regular after changing the HTTP port . Someone get me a solution ..

We can HELP get you a solution, but to do that provide us with a little more information... Appliance model Firmware version load (number users, IPS/IDS/web filtering, etc) All of the above factors may play into why you' re experiencing that issue.

Let me guess: - you try to manage the FGT via HTTP, port 80 - there is a web server behind the FGT using port 80 as well Question: if you change the HTTPS port to, say, 30443, and allow HTTPS management on the WAN port, can you then reach the FGT? And is it stable?

The information you' ve requested : Appliance model : FG100D Firmware Version : V4.0 MR3 (PATCH11) approximately 60 users UTM: AV in flow mode and IPS in the meantime, the appliance usage resource is normal in all activities . There is no any port forwarding toward another web server behind FG.. and the issue happen again some while after changing the port number . got any clue ?

If you don' t get access to WebUI do you see http error 400 like user " Dratas" descibed here: http://support.fortinet.com/forum/tm.asp?m=94042&appid=&p=&mpage=1&key=http%2Cerror&language=single&tmode=&smode=&s=#94042 I have the same problem on a 100D with 4.3.11. I have a ticket open at forti-support. They advised me to update to 4.3.12 but don' t confirm, that there is a Bugfix for this...

i' ve done it as your suggest (Upgrading to patch 12)

That was an advice from Fortinet Support. But anyway the result is disappointing. I suggest you should open a ticket at support too (if not done).

Do you have any crashes in the console or ' diagnose debug crashlog read' when the problem occurs?

You know this is a strange problem, and i have found some weird symptom on appliance . let me elaborate it : as i told, in this issue we encounter the HTTP error 400 when trying to get access to WebGUI, so today i just cleared all the cookies and caches of my browser and i just have successful to login , but some while after exploring in menus i got the 400 error again . so i thought this is the browser malfunction, but my colleague pretend that he has tried it from many systems with different browsers and the result was disappointed ... i just confused .. anyway i' ve decided to test the appliance hardware with HPQI firmware ... SOME ONE JUST HELP ME !
