Hi. I'm looking to build an application where a number of remote win2k systems on the internet connect to a central office server running XP and some recent version of SQL Server to transfer daily data.
Here's my concerns:
1) I don't have access to the firewalls on the remote systems -- they run NAT and allow outgoing connections, but there's no way to open ports. I'd think this would not be a problem because they will initiate the connection to the office computer where I do have access. On the central (office) server I just need port 1433 open?
2) It looks to me like the standard MS ODBC driver supports TCP/IP connections and can accept ip addresses as well as fqdn for server names. I don't want to try to get remote computers to have to join the office domain. I believe I can use "mixed" SQL authentication so SQL server authenticates remote users.
3) I guess my main question has to do with security -- does the standard ODBC driver encrypt the transmission? If not I'll need to set up STUNNEL or Zebedee to protect the stream.
So in summary:
1) ODBC -> SQL server can be happy with only port 1433?
2) SQL Server authentication will be fine with remote internet ODBC clients?
3) ODBC -> SQL Server isn't an ecrypted stream?
