I have Windows XP Service Pack 3 installed on a Mac running Parallels 6. Everything works fine except for FTP programmes (ie Filezilla, CoreFTP etc). If I connect from my Mac directly using Filezilla (not from virtual machine) everything works fine.

Below is the status report that I get from Filezilla 3.4.0 when I try to connect to my server.

I hope someone can help.

Many thanks,

I don't know Parallels, but my guess would be that it (or Windows) blocks some ports (which need to be open for passive FTP transmissions). – slhck May 13 '11 at 9:52
@slhck I tried disabling the Windows Firewall without success. I don't believe Parallels has any port configuration, I will double check. Thanks. – Giuseppe Romagnuolo May 13 '11 at 9:58

OK I found out what it was, it was OSX's firewall that was blocking it!

Thank you @slhck for the hint on the ports.

Ok, let me put that as an answer then ;) – slhck May 13 '11 at 10:07

For FTP connections you need to have certain ports open. In the following order, check if there are firewalls blocking it:

  • OS X
  • Parallels (I don't know if it has something like that)
  • Windows XP

Do you know how to open specific port on a Snow Leopard? It seems that apart from adding an application the the rules (which I did with Parallels but did not work) there is no interface for adding a specific port. I cannot get Filezilla to work with the Mac's Firewall on and I don't want to switch off my Mac's Firewall!? – Giuseppe Romagnuolo May 13 '11 at 10:26
@Giuseppe Hm, I think is not the main application where traffic goes through. There must be some service running in the background for network traffic. That might just be worth another question ("How to disable OS X firewall for Parallels only"). I unfortunately can't try it because I don't have Parallels. – slhck May 13 '11 at 10:34
