M4100 dhcp reservation

Good day !

 

So my M4100 is set at 192.168.1.1

I made a dhcp scope (scope1) dynamic for 192.168.1.0 / 255.255.255.0

In the dhcp server setting I made an exclusion from 192.168.1.1 to 192.168.1.99.

 

Everything works fine except that now I'm trying to make an ip reservation for a specific device.

I made a new scope (scope2), manual, entered hardware address (MAC) and client ID (MAC + 01: in front of it).

 

the device still grab an IP from the main scope (scope1) ignoring the manual reservation from (scope2)...

I just dont understand why.

I tried to specify the ip address for the scope 2 to be with the exclusion range and also outside the exclusion range without success...

Any idea ?

 

Thanks for your help !

  • Hi tlex,

    Welcomet to NETGEAR community!:smileyhappy:

     

    Maybe you need to set same configuration for the manual pool as following screenshot.

    The Client ID is (01:MAC Address of DHCP client)

    The Hardware address is none.

    The Host number is the IP address that you want to assigned. (such as: 192.168.1.254)

    The Host mask should be same as routing interface(such as: 255.255.255.0)
