IP Question

In mapping a drive for Internet shares, what TCP/IP ports
need to be open on a router? We can map the drive through
the LAN, but from the Internet we cannot get past the
router.

We have only port 80 open. For drive mapping, what ports
need to be opened?
 
Assuming that you can resolve the name of the file server to its IP address,
Common Internet File System (CIFS) (also known as Server Message Block
[SMB]) file sharing occurs over the following ports:

TCP 139 (NetBIOS Session Service)
or
TCP 445 (Direct-hosting CIFS)
 
As Joseph pointed out, it is possible. But it is not a great idea. Every
port you open increases your exposure to Internet nasties.

Have you considered using VPN to give remote clients secure access to
your LAN?
