The VersaLex application provides IP filtering that allows you to specify both a whitelist and a blacklist to control the IP addresses from which VersaLex application users can log in.
Configuring a whitelist
A whitelist allows you to specify IP addresses from which users are allowed to log in. You specify whitelist IP addresses per local user mailbox by editing individual local user mailboxes. See Configuring IP filtering for an FTP mailbox, Configuring IP Filter for Local HTTP Mailbox, Configuring IP filter for local SSH FTP mailbox, and Users Mailbox: IP Filter.
Configuring a blacklist
A blacklist allows you to specify IP addresses that restrict access to the Cleo Harmony, Cleo VLTrader, and Cleo LexiCom applications through FTP/FTPs, SSH FTP/SSH FTPs, HTTP/HTTPs, along with general web UI access through the Cleo Harmony or Cleo VLTrader and Cleo VLNavigator applications.
It is important to understand that blacklist entries will take higher priority than whitelist entries. For example, if an IP is on both lists, access is denied from that IP. Set up blacklisting by specifying parameters for automated blacklist additions or by manually adding IP addresses to the blacklist. Configure your blacklist on the Blacklist tab on the IP Filter dialog box.
