Restriction from DMZ to the internal iSeries

I have a DMZ Web Server configured with Client Access for Windows (Express tool). I'm trying to access the data source on the iSeries, but it times out with the following message, "Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[IBM][iSeries Access ODBC Driver]Connection login timed out."
This is probably due to port restriction from the DMZ to the internal iSeries. You need to keep the port number open for the sign-on server and the database server.
