Re: Net::FTP port inconsistencies

FTP uses port 20 as its data port, per default. That is, the client should listen on port 20, for the server to send data to. The passive command asks the server to designate a data port, and listen on it, which the client then connects to. (The point being that sometimes the client is behind a firewall or isnt allowed to open ports for listening). See section 3.3 of the RFC.

If you are using passive (PASV), then neither is using port 20. Possibly the IIS server has problems with passive mode? (Would be odd though) .. Try adding DEBUG => 1 to your ->new call, and gve us the results?
