Hello,
I have 3 question regarding netflow/sflow and hope in this room there are anybody who can help me.
1. As i know fortinet have netflow and sflow feature, which one is more recommended to use?
2. If we apply netflow/sflow in outside interface it's true that captured traffic only showing conversation from NATed Public IP to the internet?
3. If we apply netflow/sflow in inside interface it's true that captured traffic only showing conversation from private ip to the internet?

I am not sure which is better, probably sFlow as it has more information about the traffic, but personally I don't have experience with sFlow.
Hi, I did both, and from experience:

Hi,
I tried the sFlow and got the following result. If the sampler was set to 1/10, then when I sent 1GB of traffic, I saw 100MB in collector. If the sampler is 1/100, then I saw 10MB. If 1/1000, then 1MB. Is this the correct sFlow behavior?
Thanks.
Nobody knows. Misfortune.
