With TCP/IP you are always active but may not be able to reach the remote location. Basically when the TCP/IP program start to listen at port 397, YES it MUST be opened through your firewall, the controllers become active. Each system will try to connect to the remote system that is listening at port 397. First NETSTAT *CNN and look for: Remote Remote Local Opt Address Port Port Idle Time State * * APPCove > 406:54:06 Listen * * APPCove > 263:53:08 *UDP and if you hit F14: Remote Remote Local Opt Address Port Port Idle Time State * * 397 406:54:06 Listen * * 397 263:53:08 *UDP That means that your AS400 is configured correctly for *ANYNW. The remainder is getting the correct Host name resolution in DNS or Host table. Ahh! I mention earlier to add the host tables:HOST.SNA.APPN.IBM.COM. Did I mention that it must be all UPPER CASE! Now on the CFGTCPDMN make sure you are checking your local host table before going out to your DNS server(s). Now who ever told you that you do not need additional ports opened in the firewall is talking out of there BUTT! You MUST open 397 at BOTH ends. Christopher K.

We are still having a problem completing the connection as the controllers and devices on both machines are, indeed, active but both passthru and SNADS object transfers are failing. When trying to SNADS, the status of the job goes into a "connect" condition but then soon fails with a "failure to connect to remote" message, or something like that. Passthru has a similiar response (I think it is code '0009'). Here is a quick review which I hope can provide some peek at where we might have erred: ?? Firewall. We have been told that 400 to 400 communication does NOT need any additional ports "opened" (are they already or auto opened?) for *anynet. Some have written to say ports 397 and 9216 must be opened. Our communcation contacts say not true. Word? SUMMARY. Based on the information above, does anyone have an idea why the controllers and devices are ACTIVE without passthru and SNADS co-operating?
