I am wondering if anyone might have tested ISA server and 4D Client / = Server. 4D (4th Dimension) is a client/server database engine for both Windows = and Macintosh - it uses TCP. This seems like a simple scenario, but I did this test: Set up an ISA Server, and put a 4D Client machine on a Local Network = connected to it (192 subnet). Then, on the other side of the ISA server = (internet subnet address), put up a 4D Server. I can ping the 4D Server = machine, but when I type the IP address in 4D Client, I get a -10002 = error soon after clicking connect. The ISA server is set up to allow ALL traffic outgoing. So, all machine = are able to ftp, go to web pages, ping, etc... They just cant connect to = a 4D server! Any thoughts? Thanks, Scott
