Enter a value to determine disconnecting idle FTP connections in the No activity timeout field. If an FTP

connection is idle for the number of seconds specified, the connection is automatically disconnected.
Increase this only if you are experiencing time outs during FTP sessions.
• Default: 300
• Can be a value of 1 or greater
Specify the maximum number of simultaneous connections to allow in the Maximum simultaneous
5
connections field. 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.
• Default: 10
• Can be a value of 0 or greater
Specify the maximum connections allowed for one host in the Maximum connections for one host
6
field. This is the number of FTP connections allowed from a single PC. Once this number is reached,
subsequent FTP connections are rejected until previous FTP connections are disconnected. This value
should not exceed the Maximum simultaneous connections value.
• Default: 4
• Can be a value of 1 or greater
To keep an FTP download from timing out, enter an interval value to send a status message in the Keep
7
alive interval field. If an FTP client cannot process the status messages, disable the feature by entering
zero (0).
