Open Ports on Firewalls

Applies To: Windows Server 2003 R2

To utilize Network File System (NFS), you need to configure the firewalls running on your network. Typically, externally facing firewalls should not be configured to pass NFS or authentication requests. However, internally facing firewalls, such as the Windows Firewall in Windows XP SP2, will need configuration. You need to open ports 111, 1039, 1047, 1048, and 2049 for both User Datagram Protocol (UDP) and TCP. For complete details about ports that you must open in Windows XP Service Pack 2 to enable access to Windows Services for UNIX 3.5, see the Microsoft Support article at: http://go.microsoft.com/fwlink/?LinkId=75006.
