FTP Access control based on Ip ranges

[pmverma]

Hi all,
If a user is accessing Alfresco via FTP. Then I would like to block accessing based on IP ranges.

After googling, I found following link and I provide my configuration in alfresco-global.properties as following.
<a href="http://wiki.alfresco.com/wiki/File_Server_Subsystem_4.0#IP_Address_Access_Controls">http://wiki.alfresco.com/wiki/File_Server_Subsystem_4.0#IP_Address_Access_Controls</a>

filesystem.acl.global.ipAddressAccessControls=ip1
filesystem.acl.global.ipAddressAccessControls.value.ip1.accessType=None
filesystem.acl.global.ipAddressAccessControls.value.ip1.subnet=192.168.1.19
filesystem.acl.global.ipAddressAccessControls.value.ip1.netMask=255.255.254.0
‍‍‍‍‍‍

With above configuration, I am trying block "192.168.1.19". But after server restart, Alfresco is still accessed from 192.168.1.19 with a FTP Client.
I also tried with

filesystem.acl.global.ipAddressAccessControls=ip1
filesystem.acl.global.ipAddressAccessControls.value.ip1.accessType=None
filesystem.acl.global.ipAddressAccessControls.value.ip1.subnet=192.168.1.*
filesystem.acl.global.ipAddressAccessControls.value.ip1.netMask=255.255.254.0
‍‍‍‍‍‍

but no any help.

Could anybody please tell me what is mistake and how to configure?

Thanks in advance.

should try with .0 for the subnet instead of .*
