Can I use 192.168.1.x as the wireless network for connecting 4RE systems to the WatchGuard server?
No. The 4RE's on-board internal network uses 192.168.1.x/24. Setting the network to this IP address will cause a conflict with the internal components and will cause the DVR to become unresponsive. This would require the DVR to be returned for repair.
Firmware 4.0.4 (and newer) prevents you from setting the IP address to 192.168.1.x in the Maintenance Menu. Ensure the DVR is on the most current firmware.
