I need some help.
I am a network engineer and our network is using DHCP server but we have admin users have static IP address and these IP's have full access to all network (Outside , Firewall , internet , download....etc).
Some of normal users sometimes they take these IP's and use it when the admin laptops are off they are using these ip's specially when they need to download files from the internet (the normal users are using proxy to browse the internet but the admin users have direct access to the internet ).
If i can map the IP addess to the MAC addess for the Admin users and if any one try to use these ip address he can't connect to the network.
Can any one help me to restrict these users to don't use these IP's by using (VLAN Map, access list, MAC ...) Our access switch are cisco 3560.
Our network is one VLAN.
Any other information please tell me.
