## Overview

The **LAN** tab is the local-network view. It opens with a **LAN ports** card
carrying the same live port diagram as the Overview banner, then **DHCP
Clients**, the interfaces on which this router is itself a DHCP client and in
practice means the WAN links, and finally **Leases**, every address the
router has handed out.

Everything on the page reloads every three seconds, so leases appear and expire
as they happen. Leases are where you do the actual work here: you can pin a
dynamic lease so a device always gets the same address, or drop a lease
entirely.

## Before you start

- WAN ports are managed on the [WAN tab](/en/guides/nasnet-panel/wan/), not
  here.
- Removing a lease cannot be undone from the panel.

## Steps

1. Open the **LAN** tab.
2. Find the device you care about in the **Leases** table by searching for host name,
   MAC or address.
3. To make its address permanent, press the pin button on a lease marked
   **dynamic**. A "Lease made static" toast confirms.
4. To drop a lease, press the trash button and confirm in the **Remove DHCP
   lease** dialog.

## Reference

### Leases table

| Column | What it shows |
| ------ | ------------- |
| Address | The leased IP. |
| MAC | The client's MAC address. |
| Host | The client's host name, or empty when the client does not send one. |
| Server | The DHCP server that issued it. |
| Port | The bridge port the client is on. |
| Type | **dynamic** or **static**. |
| Status | RouterOS lease status, one of bound, waiting, offered or busy. |
| Expires | Time left on the lease. |

Row actions: pin (**Make static**, dynamic leases only) and trash
(**Remove**).

### DHCP Clients table

| Column | What it shows |
| ------ | ------------- |
| Interface | The interface running a DHCP client. |
| Address | The address it obtained. |
| Status | RouterOS DHCP client status. |
| Gateway | Gateway received from the server. |
| DNS | Primary and secondary DNS received. |
| State | **enabled** or **disabled**. |

## Troubleshooting

**"This router is not a DHCP client on any interface."** No uplink is using
DHCP, and a static or PPPoE WAN is normal and produces this message.

**"No active leases."** Nothing has requested an address yet, or the DHCP
server is not running on the LAN bridge.

**"Missing router credentials for this session."** Reconnect to the router from
the Routers list.
