Dynamic NAT configuration example 1
This section describes the Dynamic NAT configuration shown in Figure 16.
FIGURE 16 Minimum required commands
Figure 16 shows an example of a network using dynamic NAT on a ServerIron ADX ADX. The device
is acting as a gateway to connect a private network to the Internet. The private network, which can
also be considered as the inside network, is using IP addresses in the range of 10.10.1.2 -
10.10.1.254 with a 24-bit subnet mask.
The ServerIron ADX is connected to the Internet through a router. The outside interface of the
ServerIron ADX has a global IP address of 209.157.1.1. The ServerIron ADX also has a pool of
global IP addresses, which are used to map internal IP addresses.
Minimum required commands for dynamic NAT configuration.
1. Identify an internal and external interface on the ServerIron ADX. In this example, Ethernet 1/2
and 1/1 are used.
int eth 1/2
int eth 1/1
2. Assign IP addresses to the interfaces and define the outside and inside boundaries of the NAT
mechanism.
ServerIronADX(config)# int eth 1/2
ServerIronADX(config-if-1/2)# ip address 209.157.1.1/24
ServerIronADX(config-if-1/2)# ip nat outside
ServerIronADX(config-if-1/2)# int eth 1/1
ServerIronADX(config-if-1/1)# ip address 10.10.10.1/24
ServerIronADX(config-if-1/1)# ip nat inside
On Switch (S) code, enable NAT globally.
ServerIronADX(config)# ip nat inside
