From the server-side firewall's standpoint, to support passive mode FTP the following communication channels need to be opened: 1  FTP server's port 21 from anywhere (Client initiates connection)  FTP server's port 21 to ports > 1023 (Server responds to client's control port)
Once you have enabled File and Printer Sharing, you still may not be able to see other computers on the network if you have the Windows XP Firewall enabled. By default, Windows does not allow the File and Printer Sharing service access through the firewall, so you have to manually allow access.f turning off your firewall allows you to see the other computers, what you need to do on your firewall is open the ports that the traffic operates on. i.e., FTP = 21, SMTP = 25, Kerberos = 88â¦ Not too sure what ports you'll need to open to allow network browsing via NetBIOS but a simple google should help out.
