BDE connection to SQL Server over Internet - Help?

I'm trying to set up a BDE connection to SQL Server 7 where a client can
connect to the SQL server over the internet.  I've got SQL server monitoring
port 1433 and the firewall has that port open to the server, but I cannot
connect via the Internet.  ODBC connections can get to the SQL server via
Internet TCP/IP address & the BDE can also connect locally via the IP
address of the server ... but no luck with BDE beyond our LAN.

Anyone have success with that?
