The following command associates the public address with the Mitel CS-5200/5400/5600

this public IP to the Mitel CS-5200/5400/5600.

The following commands set up the dynamic NAT configuration to use a pool of public
addresses. This is not specific to this example, but it is included here to contrast static vs.
dynamic NAT.
