# Mapped IP Address List

A mapped IP (MIP) is a direct one-to-one mapping of traffic destined from one IP address to another IP address. You can create MIP addresses for tunnel interfaces and any interface in the Untrust zone.

As opposed to Dynamic IP (DIP) which translates the source IP address in an IP packet header to a randomly chosen address from a DIP pool, MIP maps the destination IP address in an IP packet header to another static IP address.

MIPs allow inbound traffic to reach private addresses in a zone whose interface is in NAT mode.

For more information on mapped IPs, refer to the NetScreen Concepts & Examples ScreenOS Reference Guide available on the documentation CD that shipped with your device and also on the Juniper Networks documentation site.

## Mapped IP List

At the top of the Interface MIP list page, you can see the interface to which the mapped IPs in the list belong. For example, you see:

Interface: ethernet3/2 (IP/Netmask: 209.122.17.1/24)

The table lists all mapped IPs belonging to the interface that is indicated at top and also contains the following information on each mapped IP:

Mapped IP/Netmask: Indicates the public IP address that receives inbound traffic that is then redirected to a host with a private IP address, and the subnet mask of the public IP address.

Host IP: Indicates the private IP address of the host to receive traffic mapped from the public IP address.

VRouter: Indicates the name of the virtual router to which the host IP address belongs.

VSYS Name: (For devices that support VSYS only.) Indicates t he name of the virtual system the administrator is currently logged on.

Configure: Click Edit to modify the entry, or click Remove to delete it.

### To Create a New Mapped IP

Click New to create a new Mapped IP. For more information, see Mapped IP Address Configuration.

### To Modify a Mapped IP

1. In the Configure column, click Edit for the mapped IP you want to modify.

The Interface MIP configuration page appears.

2. Enter the new information, and then click OK to save your changes.

For more information, see Mapped IP Address Configuration.

### To Remove a Mapped IP

1. In the Configure column, click Remove for the mapped IP that you want to delete.

A system message prompts you to confirm the removal.

2. Click Yes to confirm the removal, or No to cancel it.
