Report of total number of hosts discovered by FTD

Ditter — Sun, 15 Dec 2024 12:13:39 GMT

Hi to all,

has anybody tried to create a report with all hosts discovered from FTDs in the inside network.

I tried to create a new report template but i can not find any relevant field i could add in order to create such report.

Has anybody tried this?

Thanks

Ditter.

Go to Analysis > Hosts and Create Report. Delete all sections except the Table View of Hosts. Customize the fields included to show only the ones you want. Tweak it as desired while using Preview to show the result. Then Save for later use.

Thanks @Marvin Rhoads , i isolated the fields i needed now i can get the report. The only problem is that i am also getting the ipv6 addresses of these hosts (all the systems are dual stack) , therefore i get double or even triple and even more entries dut to the nature of ipv6. Is there any way i could isolate the ipv4 only hosts in the report?

The sorting and deduplication you are asking for isn't something we can easily make FMC do directly, as far as I know.

If you generate the report as PDF or HTML you can use some third party tools to further parse the data. For instance, I opened the PDF in Acrobat Pro and then exported to .xlsx format for use by Excel.

Some folks smarter than me with programming can probably do it via API as well.

Hi @Marvin Rhoads , in my discovered hosts table view i get a lot of hosts "marked" as NAT devices. However they are normal hosts as all the others . Any idea of why is this happening?

One "suspicion" i have is that the provide NAT services to othet hosts , but their number is huge compared to other hosts not marked as NAT device.

Any ideas? Please se the attached png.

Thanks,

Ditter

@Ditter: Sorry, but I don't have any insight regarding your question about discovered "NAT devices".
