# Set-OPNSensePortForwardingRule

## SYNOPSIS
Modifies an existing port forwarding rule on an OPNSense firewall.

## SYNTAX

```
Set-OPNSensePortForwardingRule -UUID <String> [-Interface <String>] [-Protocol <String>] [-SourceAddress <String>]
                              [-SourcePort <String>] [-DestinationAddress <String>] [-DestinationPort <String>]
                              [-TargetIP <String>] [-TargetPort <String>] [-Description <String>] [-Enabled <Boolean>]
                              [-NATReflection <String>] [-WhatIf] [-Confirm]
```

## DESCRIPTION
The Set-OPNSensePortForwardingRule cmdlet modifies an existing port forwarding rule on an OPNSense firewall.

## EXAMPLES

### Example 1: Modify a port forwarding rule description
```powershell
Set-OPNSensePortForwardingRule -UUID "a1b2c3d4-e5f6-7890-abcd-ef1234567890" -Description "Updated Web Server"
```

This example updates the description of an existing port forwarding rule.

### Example 2: Change the target IP for a port forwarding rule
```powershell
Set-OPNSensePortForwardingRule -UUID "a1b2c3d4-e5f6-7890-abcd-ef1234567890" -TargetIP "192.168.1.11"
```

This example changes the internal IP address to which traffic is forwarded.

### Example 3: Disable a port forwarding rule
```powershell
Set-OPNSensePortForwardingRule -UUID "a1b2c3d4-e5f6-7890-abcd-ef1234567890" -Enabled $false
```

This example disables an existing port forwarding rule.

## NOTES
This cmdlet requires a connection to an OPNSense firewall. Use Connect-OPNSense to establish a connection.
After modifying a port forwarding rule, you may need to apply the changes for them to take effect.
Modifying port forwarding rules may require corresponding changes to firewall rules.
