Hello...

I presume you're running Windows and talking about Windows File Sharing over the Internet. The answer would be completely different otherwise!

Considerations and Notes:

- Using Windows File Sharing over the Internet is technically no different than sharing over a LAN. I've done it before as a test. However, you don't want to do it that way because it is insecure.

- The security risk is that when you enable Windows File Sharing directly on the Internet, your PC becomes a server on the Internet. Hackers could attack your PC through the IP port used by Windows File Sharing. It is a risk that you should not take.

- It would be best to establish a VPN tunnel through your Internet connection. A VPN tunnel uses the Internet to provide a private, secure, encrypted connection between two LANs. This is not entirely without risk however. The IP port used by VPN could be attacked if there were an exploit for it.

- Special Note: Your broadband Internet Service Provider (ISP) may have a form of firewall in the way that prevents you from having a server on your PC. My cable ISP does this. Their objetive is to offer very high speed CLIENT Internet service without allowing people to offer SERVER host services. What it does is block certain IP ports. So, for example, you might be able to PING the IP address assigned to the other computer across the Internet, but won't be able to access other ports required for server functions like Windows File Sharing, VPN server, FTP server, or web server. You'll have to try it to find out.

- There are ways to copy files across the Internet that should always work: Email attachments (subject to size limits), a private FTP server (provided by an separate web host not your broadband ISP), Google GMAIL, Hotmail, etc.

Did this help with your question?

to ping for the specific port:
ping ipnumber:portnumber
ie:
ping 127.0.0.1:546
would ping localhost at port 546
if you get a ping response without port, then this will tell you if the port is available.
you can specify what port to use with vpn tunneling, you don't have to use the default.
changing the port to one of the higher numbered ports is generally more secure, as most people don't try them.
then your risk is only from someone that is really serious about hacking.
with tightvnc ( linux based, maybe for other os also ) you can limit the connections to specific ip numbers. ( requires static ip number )
the best method would be to use a hostid and a secure login procedure with the vnc server.
even if login breached if the other system doesn't have the hostid associated with the connection, it is refused.

The easiest thing to do is set up a web server to send the files you want to share. That way the general run of the mill hacker can't get on and change the files.
If you need interactive access then VSFTP is a good way to go. It has better security but you are still setting up a server.
