Re: NDLP Prevent with Fortigate

Hi Rie,

Apologies for the delay on getting a response about this query. Is this still an issue?

If so, can you advise what version of Network DLP you are using? Additionally:

- Is this Prevent appliance scanning both SMTP and ICAP requests?

- Make sure only REQMOD is sent to the Prevent appliance (it cannot process RESPMOD requests)

I also suggest you have a look at our Knowledge Base, article should be a good place to start.

Let us know if you need further assistance.

Kind regards,

Re: NDLP Prevent with Fortigate


Could you solve this issue?

i try to integrate NDLP Prevent with Fortigate and have the same issue. Also could you tell what did you paste into "Path" field on Fortigate side?


In fortinet docs I found next: "Path - This is the path on the server to the processing compent. For instance if the Windows

share name was “Processes” and the directory within the share was “Content-Filter” the path would be “/Processes/Content-Filter/”" so I need to understand what is the path on DLP Prevent server to the processing component. Any idea?

PS I tried: blank, /DLP, /reqmod but without success.

Re: NDLP Prevent with Fortigate

With other ICAP clients, the path is set to:

icap://<ip address of dlp-prevent:1344/reqmod

I see in your screenshot that the Fortigate uses a list box for the server and text box for path, so I would first try


As the path.

I would also run tcpdump on the Prevent to make sure the Fortigate is sending to the correct port

#tcpdump -i eth1 port 1344

Re: NDLP Prevent with Fortigate

Hi rtrezza,

Thnks for your reply!

I understand that this question is must be addressed to Fortinet guys but if you could help me I will be very appreciate.

When we configure icap from fortigate side we need to do 2 steps:

1. Icap Server where we can define only ip and port


2 Profile. Where we can define request\response processing with icap server from step 1 and path.


With this config and default configuration on McAfee DLP Prevent I see next communication betwen fortigate and mcafee dlp:

Thanks in advacne for your help!
