Idle scan and predictible ip id

Hi,

I'm auditing a host that has incremental ip ids. However, I am unable to
use it as a zombie for an idle scan "cannot be used because it has not
returned any of our probes". This box does have one open port, but it
only shows up with connect/syn scan - ack scan shows everything
filtered. I guess this means it's protected by some kind of stateful
firewall, and this completely scuppers idle scan.

My question is: does this firewall mitigate all the risks associated
with predictible ip ids?

Thanks,

Paul
