Hi Atno,
What I want to do is,
My client use Dynamic IP
and with Dynamic I can not block any bad user on the network within my firewall.
My firewall can only block the manual IP, but if I can clone a client IP and PC Mac address, then this way the IP and the Mac address becomes one, so I can easliy block any user who is going above the law
Hope you understand me.

Not certain why you are worried about the IP. Most firewalls have a MAC Filtering option. For example this from Belkin

If you use MAC filtering though you will need to add the MAC addresses of all clients that are allowed access. Your firewall documentation should tell you how to set up MAC filtering.

Sonicwall has a MAC filtering option
http://blogs.techrepublic.com.com/wireless/?p=227
Quote:
Organizations wishing to allow or deny wireless connections to specific systems can implement MAC filtering. When MAC addresses are entered into the SonicWALL’s MAC Filter List, you can choose to Allow or Block communications for each device that is entered. You can also enter comments, such as Guest system or Unknown workstation from neighboring company, within a Comment field to help other IT professionals better understand why certain systems have been allowed or denied specific wireless access.


Is your network hardwired, or wireless?

I haven't seen a wireless router/firewall yet that doesn't have mac filtering.

Yes you are right on the above things you mention.
I do have lan and wlan, for those on Lan they can easily be controled, I was trying to protect the wireles connections.
But I have discover that I can create an HTTP rule for all those who want to conenct to the internet.
Then I need to create users account in Sonic wall, This will prompt user for their user names and password beofore connectiing to the internet.
This wil help me to keep track on users and I can easily block a user this will be fine.
I will try to manage it this way.
thanks for your pressence, patience and help.
I realy appreciate, be blessed!
