Replacing that with :ODBC or similar solutions would require rewriting dozens of programs. : :Has anybody found a solution for this? If you are not able to limit tcp/ip access to be between the servers with Informix only (I don't know of anything you can do to achieve this), there is no current solution as far as I know. The best I can think of is that Informix enhances their communication protocol to include similar access restrictions as OpenLink has. I believe they will be willing to do that. They will of course not do this to the I-Star product so you will have to upgrade to the latest server at that time.
