I have Atomatic Teller Machine connected through 871 router to the MPLS WAN. I want to restrict the network access on the 871 network so that, only ATM machine is able to use the network based on the MAC Address Security. For all other unauthorized access must be prevented.
Note: I'm using static IP Address on the ATM Machine not dynamic.
Hope, someone must have done the above resrtiction. Please help...........
