Typically there is no need to change the Proxy port on which the transparent proxy
listens for connections.
If an FTP connection is idle for the number of seconds specified by No activity timeout,
it is automatically disconnected. Increase this only if you are experiencing timeouts
during FTP sessions.
You may specify the Maximum simultaneous connections to allow. This is the total
number of FTP connections allowed from your LAN. Once this number is reached,
subsequent FTP connections are rejected until previous FTP connections are
disconnected. More resources are consumed by virus scanning when a higher number
of simultaneous FTP connections are established.
