As some of you may have more than one network adapter, or use NT4 Server, then you perhaps want to run a server on each IP.
This setting allows you to do it : (click on )




As you see, on the demo computer there are two IP : 192.168.0.1, 192.168.0.2
Adding them to the multiIP list you can now configure users for being available on a specific IP.




This way this account will only be available for users who want to connect to the 192.168.0.1 IP Address ftp server.
It allows you to configure an anonymous user for each ftp server :
Anon_192.168.0.1 on IP 192.168.0.1 with login : anonymous
Anon_192.168.0.2 on IP 192.168.0.2 with login : anonymous
...

User can have the same login/password on the different "virtual" servers
