Used to tell if the FileMaker Client is on the same network as the FileMaker Server.

We needed a method to know if the Client was local or remote.
However, this does not account for Users connected via a VPNs as they will have a local IP.

Returns 0 if not on the same network.
Returns >0 if on the same network.

This is my Custom Function and I want to edit it


I had a similar calculation to find if local or remote (mainly for FMGo) and it works as the mobile IP is way different, but this solution is not working if someone connect from his own network home that has the same IP chain and 192.168.1 is the most common of them.

So one of my staff passes that validation, but is connected remotely.

Anyone else find another solution ?
