DHCP setup or firewall rules ?

Hello!

Could someone help me..

I have 3 subnets

  1. 192.168.1.0/24
  2. 192.168.2.0/24
  3. 192.168.3.0/24

and DHCP server with pool (192.168.2.2-192.168.2.254)

For first(192.168.1.0/24) and third(192.168.3.0/24) subnets assigned static IP addresses in DHCP server leases.
Everything works, but each user can assign IP address manually and get IP from first or third subnets.

How can I deny access to get IP manually (from first and third nets) ?

Thanks you very much!

Maker sure Your DHCP is on the LAN interface that has the subnet you want people to get a DHCP address from

For the other 2 ports that you wants statics and not have a DHCP examine whether you want to implement using VLAN

As for forcing people to not be able to use a static not sure how you can control that as anyone can go into their ip settings in windows if they are on a microsoft operating system and set a static IP
