Dynamic IP addresses changes the whole time and I don't want to constantly change and update IP addresses.
Add wildcards to your IP address which will allow for constant changes that your service provider network will make.
The wild card will look like this, and create one for each set of octets based on the values:
You can also turn the function to allow employees to clock in from anywhere which will over ride the IP security. The IP security is the basis of the system and it keeps employees from clocking in and out from home. If your network makes these changes we are unable to automatically detect when that happens. But, the above changes should take care of the issue.
It will allow HD to accept any traffic coming in from IPs beginning with that set, which will keep employees from clocking in at home.
