I have a device with a static IP configured. This device is part of a small network. I have an old Cisco RV082 dual-WAN router that I would like to use as a firewall solely for this device to protect it from rest of the network (because I could not install a software firewall on the device.). Is possible to configure RV082 such that the static IP of this device is transparent to the rest of the network (at least transparent to those that follow the firewall rules)?
Edit: Is there a possibility to add some kind of firewall hardware for a specific device on the same subnet as rest of the network?
