Blocking DHCP port
Is there a way that I can disallow newly connected WIFI devices from obtaining an IP address from my DHCP server?
Currently have the QUARANTINE group feature enabled; hence, all inbound/outbound network traffic is blocked until I release the device from QUARANTINE group. However, my Firewalla discovers several devices and place them in QUARANTINE group, but when I try to figure out the origin of these devices, I cannot find them on my list of devices.
The problem that I have is I have unknown devices are connected to my WIFI network. The firewall is doing a good job of blocking them from access local network and Internet. However, it does not block new devices from obtaining an IP address from my DHCP server (which is a Windows Server).
I believe that I should be able to create a group and members of this group cannot obtain an IP address from DHCP server. I tried several things, including create a rule which prevent all traffic to/from the DHCP server but it does not work.
