    .EXAMPLE
    $LANConfig = [PSCustomObject]@{
        deviceName = "name of the MG"
        deviceLanIp = "192.168.0.33"
        deviceSubnet = "192.168.0.32/27"
        fixedIpAssignments = @(
            [PSCustomObject]@{
                mac = "0b:00:00:00:00:ac"
                name = "server 1"
                ip = "192.168.0.10"
            },
            [PSCustomObject]@{
                mac = "0b:00:00:00:00:ab"
                name = "server 2"
                ip = "192.168.0.20"
            }
        )
        reservedIpRanges = @(
            [PSCustomObject]@{
                start = "192.168.1.0"
                end = "192.168.1.1"
                comment = "A reserved IP range"
            }
        )
