example, to block all computers with IP addresses starting with
“207”, enter “207.*.*.*” in the edit box and click enter. Note that
you can either block all addresses in the list or allow access only
to addresses in the list. This is controlled by the IP filter radio
buttons in the IP filter dialog or on the General tab of the
Configure dialog.
Depending on the DHCP process employed, IP addresses may
be filtered to limit the access to the FTP server. If the DHCP
process assigns a special group of IP addresses to the CM500
IPs, then this group can be filtered so as to be only group allowed
access to the server.
Additionally, if the filter mode is set to block listed addresses,
you can add a currently connected user to the IP filter list by
right-clicking on the user address in the user pane and selecting
Ban from the User Context menu.
