Windows Server 2003 was created by Lindows
Hi All,
i have windows Server 2003 and i wanted to create a filesharing server. im behind a router and a friend of mines told me since NAT is enabled i would a have to do some port forwarding. i dic some research on it, but they were no help. Can anyone guide me and the right directiion.
thank You!

By file sharing, do you mean a server that provides files for download only (like an FTP server), a network file server, or a Kazaa-type file sharing PC?
The reason I ask is that some of the above are not suitable for use over the internet without additional security. Also depending on which of the above you wish to implement, you will need to forward different ports.

If I understood Lindows correctly, he is talking about the common file sharing known to us in a LAN environment.
While this is possible, you should be aware of the tremendous overhead involved when transferring files using netbios over tcp/ip (port 139). The overhead is so great that a 100Kb file could take you a total of 350 or more kilobytes to download!
I've seen this problem when connecting to my company's VPN and accessing files via the network - it is highly recommended not to take this approach. You would be better off offering a ftp service as this would prove much faster and valuable.

Plus opening up ports 139 / 445 to the external world can be a recipe for disaster... definetely not something you want to do...
Even if the worms don't manage to infect, you'll be getting hit by connections like crazy... not to mention the fact that some script kiddie or the other will definetely be running an SMB bruteforcer out there.
go with SFTP.
