No keep alive over SOCKS5 proxy

After getting a tcp capture from both sides of the proxy,
it is clear that the FTP control session is timing out on
the proxy due to inactivity. This causes the ftp server to
shut down the FTP data session.
I have verified that Enable the Keep Alive System box is
checked, but there is no evidence of traffic being sent to
the proxy over the control session once the data
transmission has started.
