We would like to be able to move to 3 because of the speed increase, but are still running into this issue where not all open ports are being identified. For now, psyBNC and Communigate Pro are the only two things that we have confirmed that Nessus 3.x is missing, however, if it is missing these perhaps would miss others when we do a larger scan. Any ideas would be appreciated.

When using Nessus 3.x, either with nmap or without, it fails to pick up all open ports on a host even if the port_range variable is set to 1-65535. When nessus 2.x scans the same exact host, even with the port_range variable set to default, it picks up the open ports. The specific example we have been using for our testing is psyBNC, but it is not currently throwing a banner. Nessus 2.x is currently picking it up as being an unknown open port, but not psyBNC, because it is running on a non-standard port and has no banner (this is expected), however, Nessus 3 does not show the port as being open at all.

Nessus 2 and Nessus 3 have the same port scanners. Which version of Nessus 2 are you referring to ? (and which version of Nessus 3?)
