# New-OPNSenseDHCPStaticMapping

## SYNOPSIS
Creates a new DHCP static mapping on an OPNSense firewall.

## SYNTAX

```
New-OPNSenseDHCPStaticMapping -Interface <String> -MAC <String> -IP <String> [-Hostname <String>] [-Description <String>]
                              [-DNSServers <String[]>] [-Domain <String>] [-Gateway <String>] [-ARP <Boolean>]
                              [-Disabled <Boolean>] [-WhatIf] [-Confirm]
```

## DESCRIPTION
The New-OPNSenseDHCPStaticMapping cmdlet creates a new DHCP static mapping on an OPNSense firewall. This allows you to assign a specific IP address to a device based on its MAC address.

## EXAMPLES

### Example 1: Create a new DHCP static mapping
```powershell
New-OPNSenseDHCPStaticMapping -Interface "lan" -MAC "00:11:22:33:44:55" -IP "192.168.1.50" -Hostname "printer" -Description "Office Printer"
```

This example creates a new DHCP static mapping for a device with the specified MAC address on the LAN interface.

### Example 2: Create a new DHCP static mapping with custom DNS settings
```powershell
New-OPNSenseDHCPStaticMapping -Interface "lan" -MAC "AA:BB:CC:DD:EE:FF" -IP "192.168.1.60" -Hostname "server" -Description "File Server" -DNSServers "192.168.1.1", "8.8.8.8" -Domain "example.local"
```

This example creates a new DHCP static mapping with custom DNS servers and domain.

## INPUTS

### None

## OUTPUTS

### System.Object
Returns an object representing the newly created DHCP static mapping.

## NOTES
This cmdlet requires a connection to an OPNSense firewall. Use Connect-OPNSense to establish a connection.
After creating a DHCP static mapping, the DHCP server service may need to be restarted for the changes to take effect.
The DHCP server must be enabled on the specified interface for static mappings to work.
