Cisco and DHCP Pool Binding

Hello ,

I have setup in my Cisco 6500 switch a VLAN Interface with a public subnet . I have create for this VLAN a dhcp pool with this public subnet and also i create bindings for a mac pool with spesific ips.

This subnet will be given to Virtual Machines automatic by the dhcp and according the MAC address of each vm. Is there a way if a user try to change the IP of the VM with a static one to block whole access to this virtual machine ?

Thanks

Can you just restrict the user from being able to change the ip?  Otherwise, just create an acl that would only allow traffic to/from the ip addresses you have binded. Anything outside of that range would be denied.

Unfortunately i can't restrict the user inside the virtual machine because it is not in a domain.

As for the ACL it wont do the job for me because i have a big VLAN with public ips so if the client change to the next ip then he will have access anywhere again.

The only solution if i can bind somehow mac address and IP and if it changes ip then drop connection

Thanks

What type of VM are these? Are they using local accounts on the VM's? If so, can't you give them reduced privileges?

This VM are Windows 2012 and the users will have local admin accounts so full privileges. Thats why i must do it in the networking layer .

Route maps is what you need to configure

You can match mac addresses to IP address  in a route map sequence

if you are the gateway you can also statically set the arp for the IP to the MAC address that you want so that you will never learn a different MAC address other than that.

something like

 arp 10.0.0.0 ffff.aaaa.bbbb
