I have a Linux box and its internal interface IP address is 192.168.0.1. this machine act as a gateway and provide internet service to local clients. Client address range start to 192.168.0.2 to 192.168.0.254. All clients have admin rights to their systems so they can change their IP address. When any client change his ip address of his windows machine thats use Linux (192.168.0.1) Linux stop working and cannot accessible to others client. So how to resolve this issue ? If any client gives ip address thats using Linux box thats client should be stopped not Linux box.
