["S. Khademi" <khademi@xxxxxxxxxxxx>]

Hi, 
I have created some vlan on 3com switch and my router is cisco 3640,  now 
I want to find a way for secure my lan, I want to control my any IP 
address and mac address on my lan and vlan, my mean is if a person want 
use an ip address I give him permission, would you please help me about this 
problem?
Ps, and if I create a vlan with ipchains or ipforward on my system 
how I can control IP addresses, that no body can use them without my 
permissoin?
By regards.
