Issues with Auto Attendant WAV file uploads.

Hi All,

Hopefully I can get some direction on this problem.

I have an issue with uploading any WAV files to an AA via Director from a few remote PCs.

Scenario
========

I have 2 client PC's (supposedly identical SOE builds)...

For the successful PC when trying to upload a WAV file to AA on the server via Director, a Wireshark trace shows the following;

File Transfer Protocol (FTP)
PORT 10,1,5,37,236,92\r\n
Request command: PORT
Request arg: 10,1,5,37,236,92
Active IP address: 10.1.5.37 (10.1.5.37)
Active port: 60508

File Transfer Protocol (FTP)
200 PORT command successful.\r\n
Response code: Command okay (200)
Response arg: PORT command successful.



But for a failed PC trying to upload the same WAV, Wireshark trace shows the following:-

File Transfer Protocol (FTP)
PORT 127,0,0,1,247,151\r\n <---------------- Local host IP address inserted
Request command: PORT
Request arg: 127,0,0,1,247,151
Active IP address: 127.0.0.1 (127.0.0.1)
Active port: 63383
Active IP NAT: True <---------------- Looks like NATing is occurring somewhere on PC.

501 Server cannot accept argument.\r\n
Response code: Syntax error in parameters or arguments (501)
Response arg: Server cannot accept argument.

The end user has verified that there is no NAT on the failed PC, and each PC is SOE build identical.

I have nearly exhausted all avenues to resolve.
Any ideas would be much appreciated.
