Is there a way to do this on a Mac or a Linux box? Since the host checker is so limited for non-Windows computers, we want to at least check to make sure these users are behind a router. I would like to check to make sure that the computer they're using has a private IP address.
Thanks for the reply, DAK.
Unfortunately that only works based on their public IP address. I want to block access if the IP address assigned to their computer is not a private IP address if they are using a Mac or Linux. If they're behind a hardware firewall, they would have a private IP address on the computer itself.
There really is no host checker on those operating systems, in my opinion. How tough would it be for Juniper to give us ready-made anti-virus or firewall checks for the dozen or so products that are commercially available for Macs or Linux? I'm not an endpoint security expert. I shouldn't be writing my own because that's the best way to make a mistake.
