sql server connect : Restrict internet access using ODBC?

I was wondering if it was possible to remove internet access from a PC but,
still run tracsactions over the internet using our software program which is
connected the an internet accessable sql server via odbc? Our SQL sales
program processes credit and gift cards, because of this all of the PCs have
had internet access. Will OBDC still act as a "proxy" for us for internet

I'm sorry if I was not totally clear. The SQL box is on the same physical
lan as the PCs. Yes, I am trying to remove internet access (i.e. E-mail,
chat, browsing, etc.)

SQL Server is accessed (in this case) over the local area network (LAN), not
the Internet. It uses different ports than the browsers. I suggest you
simply disconnect the LAN from the Internet. Of course, this means no one
can use the Internet for legitimate access like corporate email, setting up
travel reservations or checking on the current activity of Paris Hilton. You
can also setup LANs that are separate from those that have Internet access
and prevent port access between the LANs that would permit outside access.

Hi James,

I'm not an expert in this area but...

When you say you want to "remove internet access" do you mean that you want
to prevent users from using browsers or email? In order to communicate with
the offsite SQL Server you'll need "internet access" but you may be able to
block some outgoing and incoming ports, restricting the internet access to
your application.

That scenario should work, if the SQL Server box is on the same internal
network, you don't need internet access to connect. You can just use TCP/IP
on the local network.
