Configuring NAT

DRAFT: BROCADE CONFIDENTIAL

Static NAT configuration example

The following example describes how to configure a static NAT entry for Inside-to-outside and

outside-to-inside translation for the network shown in Figure 20.

FIGURE 20 Example of a static NAT configuration with ServerIron ADX

Configured for inside-to-outside translation

In this example, the ServerIron ADX is configured to translate the local host IP address 20.20.5.6 to

the unique global address 15.15.15.15.

Assign IP addresses to the interfaces and, on router code, enable NAT on both the inside and the

outside interfaces. The interfaces can also be virtual interfaces (not necessarily physical

interfaces).

ServerIronADX(config)# interface ethernet 1/5

ServerIronADX(config-if-1/5)# ip address 20.20.50.1 255.255.0.0

ServerIronADX(config-if-1/5)# ip nat inside

ServerIronADX(config-if-1/1)# int eth 1/1

ServerIronADX(config-if-1/1)# ip address 30.30.0.1 255.255.0.0

ServerIronADX(config-if-1/1)# ip nat outside

On switch code, enable NAT globally.

ServerIronADX(config)# ip nat inside

The following command configures the ServerIron ADX to translate IP packets with a local IP

address of 20.20.5.6 to the global IP address 15.15.15.15.

ServerIronADX(config)# ip nat inside source static 20.20.5.6 15.15.15.15

Configured for outside-to-inside translation

To configure the ServerIron ADX shown in Figure 20 for outside-to-inside translation as well, the

only requirement is that outside interface must be configured with an additional IP address in the

public subnet, in this case 15.15.15.0/24 as shown in the following example.

Remote Server
