Internal Interface: Static IP Address

The Internal (LAN) Interfaces on the X family device use static IP addressing.

When configuring Static IP addressing on the internal interfaces, you also have the option to allow the

device to perform Network Address Translation (NAT), which allows all the computers on your

network to share one IP address.

Configure a Static IP Address on an Internal Interface

STEP 1

From the LSM menu, select Network > Configuration > IP Interfaces.

STEP 2

On the IP Interfaces page, click the Create IP Interface button or select the Edit icon for the

interface that you want to edit.

STEP 3

On the Edit/Create IP Interface page, select Internal as the Interface Type.

STEP 4

Specify the Internal Interface Configuration information in the appropriate fields:

• IP Address — the address on the IP subnet that you have allocated for this interface

• Subnet Address — the subnet mask associated with the IP subnet

STEP 5

To allow all the computers on your network to share one IP address, check Enable NAT. Then,

for the Public NAT address, either:

•Select Use External Interface IP address.

•Select Manually Enter and enter a public IP address allocated by your ISP that is on the

same subnet as the external interface.

STEP 6

Click Save.

Click Cancel to return to the NETWORK - Interfaces page without saving the changes.
