This may be an easy networking question. I have a device that always has a static IP address (DHCP is not allowed). This address can change depending on the user's need. I want to use a router for two other devices to be able to talk to this device. I don't want to have to change the configuration of the router every time some one changes the static IP on the device.
So router will be set up to DHCP starting at 192.168.1.100 My pc and another device(2) will lease ip's from the router. PC will be over WIFI and device(2) will be hardwired. The device(3) with the static IP will be 10.118.205.143 How do I set up the router so device 3 can talk to the PC and device 2?
