RV082 Uploading large files via FTP fails

We are uploading large files via FTP through our RV082 to the "internet". The upload , via FileZilla, of the largest files can take hours. The largest files always fail at 100%. The symptom is typical of a problem when the FTP "control channel" is timed out by the router and dropped.

"However, many routers and firewalls drop connections that have been  idle for less than 2 hours and 4 minutes. This violates the TCP  specifications (RFC 5382 makes this especially clear). In other words, all routers and firewalls  that are dropping idle connections too early cannot be used for long  FTP transfers. "
