web filter for https request

[max71]

Hello , 

I run into this issues, 

internet -> fortigate -> fortiauthenticator (with reset password service)

everithing working correctly also fortytoken service , but i would like to restrict the access only for request addressed to https://urlfortigate/portal/selfservice/reset_password

this url open a web page on 443 for reset password service.

I wish to block every others web page that coming from internet to fortiauthenticator.

i though a webfilter that permit only 

urlfortigate/portal/selfservice/reset_password -- simple -- allow

* -- wildcard -- block

but another configuration is put the firewall policy using a certificate inspection.

If i use this config when the internet user can try to reach the fortiauthenticator web page to reset own password obtain that " you are not allowed to access this resource" ... i think is a fortiauthenticator message but i do not understand where this message born ... 

someone has tried to experience this issues ....

thank you

Hi Massimo

If you want to allow or deny a HTTPS URL in a web filter then you need SSL deep inspection.

Hello Massimo

The fastest way is to use the FGT's predefined "deep-inspection" profile, or clone it and customize it.

Then on FGT, download the CA certificate "Fortinet_CA_SSL" (from System > Certificates) and install it on your clients.

After that FortiGate can do deep inspection for your client's traffic without displaying certificate warning on your browser.

In case your FAC is already your CA, and you want to generate the intermediate CA with FAC and import it on FG, here is how to do.

Hope it helps.
