DHCP Server with NAT Configuration Example
In this DHCP Server with NAT example:
T The clients are using dynamic IP address assignment and use the Ethernet
interface of the router as the next hop router (default gateway).
T The DHCP server assigns private IP addresses which are converted to public
IP addresses by NAT.
T The network interface must be numbered.
T The router is configured as the DHCP server giving the private IP addresses
to the clients.
T The Ethernet interface is in private address space. NAT is used for one-to-one
mapping of addresses.
The command line syntax for this example, where x is the number configured for
the sub-interface, is:
ip nat pool public 192.128.22.1 netmask 255.255.255.0
access-list 1 permit 10.1.1.0 0.0.0.255
ip nat inside source list 1 pool public
interface ethernet 0
ip nat inside
interface serial 0.
x
ip nat outside
Public IP Addresses for NAT Private IP Addresses
192.128.22.1 10.1.3.2
192.128.22.2 10.1.3.3
