nmap scan results and nessus 2.2.2

[Roger Grandjean]

Signature MailHi,
I just did an upgrade to the new version 2.2.2

My goal is to use nmap scan results and let nessus scanning only the open
ports found by nmap.

For this I did the following:
- Added the nmap results (V3.75, and used the switch -oN for output) in:
Prefs/NMAP/File Containing grepable results
- Enabled "Consider unscanned ports as closed"
- Disabled all Port Scanner but Nmap (NASL wrapper)
- enabled KBSaving
- disabled Ping

But nessus is still scanning all ports of the target.

I searched in the mailing lists and Web, but did find conflicting
information.

Did I made a mistake or is this not possible?

Many thanks for any hint, Roger
