Hi Bobby,
Download a tool called no-ip from the link below,
http://www.noip.com/client/DUCSetup_v4_0_2.exe
Install the tool in each location wherein internet has no static ip address.
You need to sign up at http://www.noip.com/ and required to create a host name.
Follow below steps in the tool,
1. Open the installed tool with username and password which you created at http://www.noip.com/
2. Click on 'Edit Hosts' button
3. Select the hostname for the location
See the screenshots attached.
In Lenvica HRMS you need to put the host name instead of ip address. The host name carries the ip address of that location.
See the screenshot attached.
Regards,
Rijo
