Hello I recently purchased the physical firewall "Firewalla" red from firewalla.com. It's caused a lot of connection problems for my router CG3000DV2. It's supposed to work by using ARP spoofing. My wifi for my phones and one computer just constantly connects and disconnects. Now I am plugging in my ethernet for that computer, which seems to work. I am just wondering if there will be hardware damage if these connection drops keep happening.
