DHCP Multiple MAC to one IP

DCALS

Hi,

Is there any way to map a static IP to multiple MAC addresses?

In UTM it was possible just by adding all the MAC addresses to a host object, and whichever MAC was presented to the DHCP server, it would get that IP address. I get that there are pitfalls to doing this but I've never had a problem with it.

This is really useful as most devices now mask their physical MAC addresses as a tracking avoidance measure, and the virtual MAC is only changes when the SSID changes (OK, a couple of other scenarios, but it's generally mapped statically to the SSID). I'd like my kids devices to get the same IP regardless of which MAC address is presented so I can manage their traffic through content filtering.

TIA

    Hi,

    there is another way to limit you r children's internet access. Assign fixed IP in the DHCP server to a MAC address. Then create a clienteles user based on the IP address and then create a clientless usergroup.

    In the firewall rules that you allow your children to use change the access to match known users. Doing this will stop them changing IP addresses by changing MAC addresses. You will need to do this for all your rules including your own devices.

    If you have a range of IoT devices you can do the same thing and create a clienteles user group for them.
