SYNOPSIS
Creates multiple VLANs and interfaces for a subnet on an OPNSense firewall.
SYNTAX
New-OPNSenseSubnetVLANs -Device <String> -Subnet <String> -VLANStart <Int32> -VLANCount <Int32> [-Description <String>]
[-DHCP <Boolean>] [-DHCPStart <Int32>] [-DHCPEnd <Int32>] [-DHCPDNSServer <String>]
[-DHCPDomain <String>] [-DHCPLeaseTime <String>] [-WhatIf] [-Confirm]
DESCRIPTION
The New-OPNSenseSubnetVLANs cmdlet creates multiple VLANs and interfaces for a subnet on an OPNSense firewall. This is useful for quickly setting up a network with multiple VLANs.
EXAMPLES
Example 1: Create multiple VLANs for a subnet
New-OPNSenseSubnetVLANs -Device "igb0" -Subnet "10.0.0.0/16" -VLANStart 100 -VLANCount 5 -Description "Department VLANs"
This example creates 5 VLANs starting at VLAN 100 on the igb0 interface, with subnets derived from 10.0.0.0/16.
Example 2: Create multiple VLANs with DHCP enabled
New-OPNSenseSubnetVLANs -Device "igb0" -Subnet "192.168.0.0/16" -VLANStart 200 -VLANCount 3 -Description "Guest VLANs" -DHCP $true -DHCPDNSServer "8.8.8.8,8.8.4.4" -DHCPDomain "example.com"
This example creates 3 VLANs starting at VLAN 200 on the igb0 interface, with subnets derived from 192.168.0.0/16, and DHCP enabled with custom DNS servers and domain.

CommonParameters
This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutVariable, -OutBuffer, -PipelineVariable, -Verbose, -WarningAction, and -WarningVariable. For more information, see about_CommonParameters.
INPUTS
None
OUTPUTS
System.Object

NOTES
This cmdlet requires a connection to an OPNSense firewall. Use Connect-OPNSense to establish a connection. This cmdlet creates multiple VLANs and interfaces in a single operation, which can be useful for setting up a network quickly. The subnet is divided into smaller subnets based on the number of VLANs requested.
