Ken, That web page is no longer active. We are trying to decide if using 447 for these files, internal or otherwise, is a problem on the CRTDDMF command.

When I saw port 446 I did some further research. 446 is the DRDA port. As I already mentioned, 447 is DDM without SSL and 448 is DDM with SSL. When you start the DDM TCP server, it listens on all three ports. If you look at CRTDDMF, you will see that the default for port is *DRDA. When this is mapped to the service table, it becomes port 446. For non-SSL connections you can use either port 446 or 447 on the CRTDDMF command. IBM recommends that you use 446 for clear and 447 for VPN: http://publib.boulder.ibm.com/pubs/html/as400/v4r5/ic2924/info/db2/rbae5mst1 12.htm I would suggest that you have port 447 opened through the firewall, and specify PORT(447) on the CRTDDMF command for all files pointing to that external customer. Use CHGDDMF to change the port for any existing files pointing to that customer. Continue to use the default of PORT(*DRDA) for your DDM files for internal use. Having the firewall opened for 447 and *not* for 446 will help insure that only the files that you specify wanting going outside your LAN will do so, both from the programming point of view and from the firewall point of view.
